ArcGIS Insider: GIS for Everyone, By Anyone

Thursday, October 27th, 2011

Great post on the ESRI insider Blog by Bern Szukalski on the benefits and simplicity of using ArcGIS Online to create web-based map templates.  I really like the capability ArcGIS Online brings to those of us without a server to publish web-maps.  Keep up the great work ESRI.

Here is the post in its entirity:

Earlier this week I was meeting with one of the directors of a large state agency. Among other topics we discussed, he told me that his organization was adopting a policy to move away from custom application development. Whenever possible they would serve internal and public needs with off-the-shelf applications, or better yet, with those that can be easily custom-configured without the need for programming.

When asked why, he explained the last custom application they’d deployed had to be abandoned – the programmer had left for another job, had taken knowledge of its internal workings with him, and they were unable to hire (because of budget constraints) the programming expertise needed to make the necessary updates to the application.

What color is your parachute?

This same sentiment was echoed while I was visiting with a user in Florida earlier this year. They’d also been stung when several programmers left, leaving behind a key public application that they could no longer maintain.

But before I incur the wrath of developers everywhere, it’s often the case that a totally custom application is the only way to provide a finely tuned user experience, or bring into play additional capabilities and components that are essential to the target user. You can only go so far with a configurable application. Nevertheless, configurable applications are easy to maintain and deploy, can be created more quickly and easily than ever before, and perhaps most importantly can be built by just about anyone.

For example, using ArcGIS Online I can assemble a map and configure how the user interacts with it, including choosing from a variety of basemaps, adding my operational layers, adjusting layer transparency, setting display scales, and also configuring what the user sees and experiences in the pop-up window when they click a map feature.

This easily authored webmap is now a building block that can be used in configurable templates that can be published directly from ArcGIS Online (see this blog post for more details), providing the ability to build a custom-configured application and deploy it literally in a matter of minutes.

In the past, doing all of the above and lifting something by coding from the ground-up would have taken a long time and a lot of skill.

A custom-configured application being authored with an ArcGIS Online map. Simply fill in the blanks and check the boxes to include the tools you want.

For more customized and extensible solutions, ArcGIS Viewer for Flex has been popular among Esri users since its introduction, and there is also a configurable ArcGIS Viewer for Silverlight, currently in beta, that leverages the same webmaps and offers the same ease of configuration; both allow you to build custom applications with little or no programming skills.

The ArcGIS Viewer for Silverlight application builder even lets you plug-in geoprocessing tools to extend the applicaton’s capabilities.

While visiting a local government user a few months ago, I spoke with one of the GIS staff members who had been building a custom application using ArcGIS Viewer for Flex. He said he had chosen it not because he was particularly interested in Flex, but because he found it very easy to create a custom application even though he was not a programmer himself.

“Esri has always built great developer tools for programmers and software for the GIS professional,” he told me. “My problem is I want to reach non-GIS users in my organization and post some public-facing apps. Now for the first time I feel empowered. Even I can build custom applications.”

It’s clear that it’s easier than ever for anyone to build simple custom applications, and all you need is a browser or a text editor. “This isn’t just GIS for everyone,” he went on to say. “It’s GISby anyone.”

I couldn’t agree more.

ESRI TV: What’s New in ArcGIS Online

Tuesday, October 18th, 2011

ESRI just released the latest in their ESRI TV video services.  The latest shows us “What’s New in ArcGIS Online.”  I really like the capability ArcGIS Online brings to those who don’t have a server to publish their work online.  I think as this capability matures it will help ESRI catch up to the head start they have given Google Earth and Google Maps.  It is very interesting to see the race to capture the “economy and power of free.”

 

PostGIS Version 2: A Game Changer?

Tuesday, October 11th, 2011

There is a great post over on GeoRelated.com about PostGIS Version 2 being a game changer. Good summary of how PostGIS Version 2 relates to PostGRES and the options PostGIS Version 2 provides.  Here’s the post:

PostGIS Version 2: a game changer?

PostGIS for PostGres

For many years there has been a limited choice of geodatabases when looking for a single solution for all geodata models. Only Oracle and ESRI offered comprehensive coverage of spatial models. OracleSpatial provided database models and algs for vector, network, raster and topology in addition to the usual database refinements and in database geocoding. ESRIoffered ArcGIS Server with comprehensive support for Vector, Network and raster models but left topology to the clients and had no offering for geocoding.Competitors such as PostGIS, MapInfo Spatialware, Microsoft SQL Server and MySQL only offered support for vectors.

It seems the status quo may be about to change. The elephant in the room has started to shuffle its feet towards the finish line. PostGIS version 2.0 not only has big plans but appears to a considerable way into delivering the promise of support for network and raster models. For those of you in the US a tiger geocoder is also available. It looks like the initial support will provide a reasonable coverage of raster and topological models but as always seems to be the problem with open source projects there is very little supporting visual tools.

Raster
Raster support is delivered through dedicated database data types for raster and GDAL based PostGIS drivers to support a wide range of raster formats. There is reasonably rich support for a first edition including:

  • Range of functions to access raster metadata
  • Raster band manipulation
  • Raster processing
    • Raster value manipulation/calculation (Algebra, reclass, value manipulation)
    • Reprojection
    • Vector to raster conversion
  • Transform to GDAL formats

Topology
Support for topology is also provided using PostGres data types. The implementation looks less mature than the raster model appearing to offer predominantly CRUD and import/export style capability only at this stage. There are also limited support for transforming data into the topological model in the database.

Vector  Geometry, Geography and Linear Referencing
PostGIS already has comprehensive support for vector geometries including 2D, 3D and linear referencing. PostGIS also supports geography types often used for global representations in its vector model.

PostGIS v2 will be worth watching in 2012 as it heads strongly into the world of GIS. The open source community makes a strong step forward with this release.

 

The Future of Cloud-based GIS Analysis with ArcGIS Online

Thursday, October 6th, 2011

Last August the ESRI Insider posted Bern Szukalski’s ideas on the future of cloud-based GIS analysis.  We heard some of this during this summer’s ESRI User Conference, but it is good to see it put in writing.  Here is the post:

The cloud is growing in importance for GIS professionals, with cost efficiency, scalability, and flexibility as major drivers. We can see the beginnings of cloud options for many organizations with the ability to run ArcGIS Server in the cloud and also via Esri’s managed services in the cloud.

On a similar, but yet somewhat different and exciting frontier, ArcGIS Online is a key part of the Esri vision for ArcGIS in the cloud. However, up until recently the focus for ArcGIS Online has been on the data part of GIS – making and sharing maps, apps, and other resources, and organizing online communities.
At the 2011 Esri International User Conference we introduced new ArcGIS Online capabilities – hosted services from Esri that enable anyone, not just GIS professionals, to be able to publish Web services using CSV files, shapefiles, and other sources. These capabilities also enable GIS users to publish maps via hosted services directly in the cloud from their ArcGIS Desktop, leveraging data in their enterprise and making ArcGIS Desktop the premier dashboard for Web publishing.
Currently in closed beta, these emerging ArcGIS Online capabilities will enable anyone to publish geographic information in an efficient, scalable, and cost-effective manner. And perhaps most importantly, they will make publishing GIS services that can be accessed by anyone easier than ever before.
During the Esri User Conference plenary Jack Dangermond spoke about the evolution of ArcGIS Online, and Jeremy Bartley and I demonstrated new capabilities that included publishing web services directly via ArcGIS Online and ArcGIS Desktop:
As significant as these capabilities are, they are focused on publishing maps and layers. But what about the ability to use ready-to-run geoprocessing tools and perform analysis via the cloud?
To answer that question, here’s an Esri Insider peek at some very exciting work in progress from the ArcGIS Online and ArcGIS Explorer Online development teams. Below is a screen capture showing the current development version of ArcGIS Explorer Online using cloud-based buffer and clip services to find the locations of wells within 200 meters of any stream:
The capabilities will include a long list of what could be described as “classic” ArcGIS capabilities, before only available to GIS professionals but soon offered via cloud-based services to non-GIS professionals alike. These promise to change how ArcGIS can be used, leveraging GIS throughout existing organizations and empowering many new users with GIS capabilities.
These capabilities will also be available in a variety of applications including the built-in ArcGIS.com map viewer, configurable Flex and Silverlight applications, and Web APIs. Stay tuned for more announcements over the next few months.

GIS On The Web Is OK, Sometimes….

Wednesday, October 5th, 2011

Mapbutcher has a great post on Web-Based GIS.  He makes some good observations and provides some great examples about how difficult and complicated the mapping tools have been in the past.  I appreciate what he has to say, and I have a some comments:

I think part of the frustration we have as GIS Professionals is that we sometimes fail to understand the separation between the data authoring tier of software and the data presentation tier of software in our GIS.  With the availability of cloud storage and a larger emphasis the last few years on data sharing through Service Oriented Architecture and OGC Data Standards I believe we have inserted the third tier of data sharing between the data authoring and data presentation tiers.  As a GIS Professional I hated it when advocates of Google Earth or Google Maps would talk about their system being a GIS.  Both programs are great data presentation tools, but not very good data authoring tools.  But, today I can author data using my favorite ESRI software and share it via web services so that the user can display it on their presentation tool of choice. I think the creation of the data sharing tier has helped many users have a more positive experience using geospatial data and at the same time has opened up what we do to an entirely new user base, one that loves using geospatial data, but doesn’t want the complicated data presentation tools we have used in the past.

I think we currently have a good assortment of web-based data presentation tools (ArcGIS Server, Google Maps, GeoServer, ArcGIS Online). What I would like to do next is to create a community of GIS Professionals who collaborate together to produce a great set of free open source web-based data authoring tools that we can all benefit from.

I’d love to hear your comments.  If any of you would like to discuss off-line you can reach me at rick.marshall@verticalgeo.com

OpenLayers 2.11 Released

Tuesday, October 4th, 2011

OpenGeo has announced that Open Layers 2.11 has been released.  VerticalGeo has been using Open Layers 2.10 and it has proven to be a powerful open source web-based visualization platform.  Open Layers does a great job of combining services and static content into a web-based map.  You can read the OpenGeo release article here:  Link.

VerticalGeo will be adding a “Maps” tab this week to our website where we will showcase what some of the open source mapping applications can provide.  We plan to open our “Maps” tab with an Open Layers Map.  These maps will not always be a finished product, but will contain some maps that are works in progress.

SlashGeo Poll: Esri ArcGIS Online vs Google Earth Builder?

Tuesday, October 4th, 2011

SlashGeo conducted a poll to find out which platform people preferred with regard to the ESRI ArcGIS Online vs Google Earth Builder debate.  The results are totally split.  Here are the results of the poll:

ESRI ArcGIS Online will prevail:  24%

Google Earth Builder will prevail: 24%

Both will be successes in their own way: 42%

Microsoft Bing Maps will rule them both: 2%

VerticalGeo is an avid user of both ESRI and Google Products.  This poll should have been a little more explicit in the question it asks.  ArcGIS Online and Google Earth both both do a great job with the presentation tier when producing geospatial data.  Neither do a very good job with the data authoring tier when producing geospatial data.  As far as VerticalGeo is concerned the ESRI suite of software products can’t be beat with it comes to authoring geospatial data.  The ESRI suite of software tools though is very expensive.  I believe there will soon be a proliferation of open-source geospatial creation and presentation tools that will compete against both ESRI and Google Earth.  What we really need if we want to develop a geospatial powerhouse are the robust tools that ESRI provides with the open source pricetag.  VerticalGeo will be venturing into the open source market to help provide just that.  We intend to combine cloud computing, open source tools for geospatial data authoring and maintenance, with a top notch presentation layer, all with a web-based interface, for free, in an attempt to help guild a community of geospatial users that will have a new alternateive to the ESRI vs Google Earth debate.
