MyGeoCloud ties PostGIS, MapServer, TileCache and OpenLayers together is a new OpenSoure project and a web service. It offers geospatial storage, WMS and WFS-T services for accessing data and transactions. Besides that it offers a built-in web mapping client and online editing of data. But MyGeoCloud is also a platform on which you can build your own location based web applications using a JavaScript API.

The core component of MyGeoCloud is the PostGIS database software, which is used for storage and geospatial operations. MapServer is used for map rendering and for tile caching TileCache is used. OpenLayers is used for the web map clients. The WFS-T service is implemented in the code base.

The goal is a all-in-one solution for storage, geospatial operations, geospatial web services and web mapping.

PostGIS vs Oracle Spatial: PostGIS Wins

Unless you're new here, you've heard of PostGIS several times. It's really hard to find documentation about spatial database benchmarks since, if I'm not mistaken, proprietary software licenses often prohibit publicly sharing such benchmarks (am I right?). And I guess there's at least one good reason for this: doing fair benchmarking is difficult to accomplish. But here's one (currently available) benchmarking report comparing PostGIS (PostgreSQL) and Oracle Spatial.

From the conclusions of the 46-pages report: "From the experimental results that we saw, we can conclude that Postgres performs better than Oracle 11g both in the Cold Phase and Warm Phase. Though in few queries Oracle 11g performed better but on the whole Postgres overpowered Oracle 11g. In the warm phase in 3 out of 4 queries Postgres performed significantly well, from this we can conclude that Postgres has better automatic memory management capabilities and page replacement policies. [...] Since Postgres uses the underlying GEOS (Geometry Engine - Open Source) library functions for implementing the geometric operations whereas Oracle 11g implements them on its own, and since in majority Postgres performs well, we can conclude that GEOS geometric algorithms are more efficiently designed than Oracle 11g. And also Postgres planner is more efficiently designed to take advantage of any available indexes to use in queries for achieving better performance whereas in Oracle 11g we saw that we have to specify them explicitly through functions."

Here's what Paul Ramsey of the PostGIS fame has to say about it: "Methodologically there are two obvious issues: one is that the Oracle database was on Windows while the PostGIS database was on Linux; the other is that neither database got any tuning, they were both installed and run with default parameters. However, this is one of the nicer comparisons I have read: concise, focussed and with enough technical detail to evaluate what's going on."

Batch Geonews: 180,000 Free OrbView-3 Scenes, Car AR Driving, PostGISonline, Bing Maps Updates, Autodesk and Pitney Bowes Alliance, Obesity and Car Travel, and much much more

​This batch mode edition is unusually long. It covers the past month and a bit more. Yes, that's way too much and I won't try to repeat the experience ;-) Here's what I considered pertinent enough to share with you. Exceptionally, in some cases I haven't gave attribution to the source of the news, thank you for your comprehension.

Slashdot Discussion: Open Source vs Proprietary GIS Solution?

Ok, I'm almost back behind the helm and I expect it's going to take me at least a week to catch up the geonews, but you'll get them.

During my absence last week, Slashdot ran a discussion named Ask Slashdot: Open Source vs Proprietary GIS Solution?

Their summary: "As the Project Manager for a non-profit looking to implement a tech project, I am running into a few dilemmas, and as a casual Slashdotter I could really use some help. I'll start with a brief explanation of the project. We research issues in Canadian Immigrants, and found that there was a lack of recent, unaggregated information. As we dug further, we found that some data was available, but there was no central repository. Therefore, we are building a web based service to collect this data, with the intent of having it display in Google Maps and then be downloadable as a CSV file that is readable in GIS software such as ESRI Arcsoft, so that data may be visualized."

Like a lot of Slashdot discussions, the value is in the moderated comments.

GeoCat Bridge v1.1. - Publishing Open Data using Open Standards




Publishing Open Data using Open Standards

GeoCat - The Government Geographic Data Publishing Company introduces GeoCat Bridge™ v1.1 

Bennekom, 10 January 2012 - GeoCat Bridge™ is designed to publish geospatial data and metadata on the Internet with a click of a button. GeoCat Bridge is an Esri® ArcGIS® Desktop extension. Publishing is done through Open Standards on a proven Free and Open Software (FOSS) server platform. Numerous government agencies, universities and privately held companies are satisfied users of Bridge version 1.0

Open Data - Open Standards!

Using a high performance server solution with unparalleled support for OGC services, data providers can deliver Open Data through Open Standards. Publishing data through Open Standards is critical to make your work a success. It allows consumers to make optimal use of your data.

Bridge has been optimized to work with the GeoServer map server and the GeoNetwork opensource metadata catalog. This free and open source server platform publishes your data in the most common data formats. Your data can be combined with Open Street Map, Google Maps™, Bing® or other base maps. 

“GeoCat Bridge is the long awaited product that promises to fill the gap between our open - and closed source hybrid geospatial frameworks” according to Thijs van Menen from Rijkswaterstaat (Ministry of Infrastructure and the Environment, The Netherlands). “Specific knowledge on how to make services is no longer needed. Finally we can fulfill the needs of our staff by providing them with a tool to make services by themselves in an easy way”

Comply with the INSPIRE Directive

GeoCat Bridge makes it extremely easy to comply with the European INSPIRE directive. You can create INSPIRE View Services with related metadata that complies to INSPIRE or is based upon an even more specific country profile (check availability). 

”The combination of ArcGIS Desktop and publishing data to an open source server platform in accordance with INSPIRE regulations is exactly what our customers need” said Sjaak Dieleman of Nieuwland Geo-Informatie “It is one of the main reasons why we were asked to build the INSPIRE services for all 25 Regional Water Authorities and the Department of Cultural Heritage (RCE) in The Netherlands”

New in Version 1.1 - Exhaustive Symbology and PostGIS Support

With the introduction of Version 1.1 a lot of improvements were implemented that contribute to an even better end-result and user experience. An exhaustive list of complex symbols is supported allowing a one-on-one conversion from Desktop to Web Map. Publishing map legends, ArcGIS 10 support, GeoSticker support and ArcSDE layer support have been added or further improved. 

Another major step is the support for PostGIS. It is now possible to upload data directly into a PostGIS database and configure map services on GeoServer using that data store. This can dramatically boost your map server performance.

“GeoCat Bridge is a key part of our Neftex Earth Model publishing workflow, enabling us to easily replicate the geological symbols used to style our ArcGIS produced content” said Alex Rushfort of Neftex ”Now we can deliver Web Map Services to our international oil industry clients through GeoServer, retaining the familiar appearance of our desktop GIS data products”

You can do it!

No advanced skills required! As a Bridge user you can fully enjoy all of the relevant functionality GeoServer and GeoNetwork have to offer without the need to be a web mapping or metadata expert. Map services and metadata are automatically linked, complexity of map symbology is no longer an issue, preview images are automatically generated and much, much more. 

“We are very excited to offer the GeoCat Bridge plugin to users of the OpenGeo Suite” said Chris Holmes, OpenGeo President ” This will greatly improve workflows for our users of Esri Desktop software, and make it much simpler for everyone to put their maps onto the web"

Pricing & Availability - Try Now for Free

GeoCat Bridge is available worldwide for a retail price of €1200,-  for a single Standard license and €1500,- for the Premium version (Prices Excluding VAT). More details, also regarding other types of licenses and volume discounts, can be found on

During the month of January 2012 we offer you a one week FREE trial license to give you the possibility to experience all functionality first hand ( In addition to the Bridge software GeoCat offers premium support contracts and services on GeoNetwork and the OpenGeo Suite to get you up and running quickly.
