Here's the recent open source geospatial news.

Open Source 'Google Vector Layers' Project

Mapperz made me aware of the open source Google Vector Layers project, allowing you to overlay your data over Google Maps.

Here's what it is: "Google Vector Layers allows you to easily add one or more vector layers from a number of different geo web services to a Google Maps API based application. Currently there's support for ArcGIS Server, Arc2Earth, GeoIQ and CartoDB with more planned."

​And how it's done: "Google Vector Layers works by listening to map events (pan and zoom) and then fetching features within the map bounds after each event. This method works great for data sets with lots of features that you want to interact with, but not load all at once."

There's demos if you want to try it live.

Open Source jQuery Plugin for Creating Subway-style Map Visualizations

Via O'Reilly I learned about this open source jQuery Plugin for creating subway-style map visualizations directly in HTML5. Now at version 0.5.0, the subwayMap Plugin already creates nice maps.

The intro of the provided step-by-step guide: "Here is a guide to using the Subway Map Visualization jQuery Plugin. Before you get started, there’s one thing you’ll want to keep in mind — beautiful subway maps are never automatic; they are almost always the result of care in design and placement to ensure that the resulting map is functional, legible and beautiful. This plugin is just a tool…you will still need to plan and design your map in order to produce a good result."

Grontmij to Provide Expert, Local Support of OpenGeo Suite to Scandinavia

Copenhagen, DK & New York, NY, December 19, 2011 — Grontmij, a leading European engineering consultancy and OpenGeo producer of the OpenGeo Suite, have announced a reseller agreement that will bring the OpenGeo Suite Enterprise Edition to Scandinavia.

 

OpenGeo is well known for its contributions and leadership in the development and evolution of powerful open source geospatial technologies. The OpenGeo Suite offers a fully integrated open source geospatial platform for serving maps and data through web applications, mobile devices, and desktop clients.

FDO Toolbox 1.0 Released

As Jackie says it, after "3 years and 1251 revisions in the making. The 1.0 final version of FDO Toolbox is finally here."

​The FDO Toolbox is described as a "multi-purpose geospatial tool to create, analyze, process and manage spatial data. It is written in C# and uses the Feature Data Objects (FDO) API".

And we can head to the OSGeo website for a reminder of what FDO is: "FDO Data Access Technology is an API for manipulating, defining and analyzing geospatial information regardless of where it is stored. FDO uses a provider-based model for supporting a variety of geospatial data sources, where each provider typically supports a particular data format or data store. FDO (“Feature Data Object”) is free, open source software licensed under the LGPL."

We mentioned FDO quite a few times in the past. I'm no expert, but I believe FDO is mainly used and part of Autodesk's MapGuide Open Source and is sometimes considered as a competitor to GDAL/OGR. What have I missed?

uDig 1.3.0 Released

With uDig 1.2 released over a year ago, let's welcome uDig 1.3.0, an open source desktop GIS based on Java.

From new features from the release notes:

  • Area of Interest support - define your area of interest based on CRS, current screen or a bookmark
  • Filter the Table view using the current area of interest - a great way to focus on what is on screen
  • Updated Info and Profile tool for raster data
  • Teradata support
  • Spatial Toolbox view allowing access to OMS3 processing; with tutorial!
  • New import and export formats: CSV and KML

Total Open Station: Open Source Data Tool for Total Stations

Via the OSGeo-Discuss list, I learned about the open source software named 'Total Open Station' (TOPS), for downloading and processing data from total station devices. TOPS is currently at version 0.3.

Here's why TOPS is different:

  • it is free software released under the GNU GPLv3 license;
  • it works on any operating system, including mobile platforms like OpenMoko;
  • it is designed to support as many devices and formats as possible, all within the same program, opposed to having one program per device.

​Also in the surveying and field measurement and monitoring category, V1 mentions a Datalogger Web Services API.

CartoDB: Open Source Cloud-Based Geospatial Platform

With all the discussions about geospatial in the cloud the past few months, via Mgeospatial, I learned about CartoDB, an open source cloud-based geospatial solution. Amongst the current users, they count the NASA and the UNEP.

Unfortunately, with its website alone, it's real hard at the moment to learn about the current features and capabilities. They do have a developers section. And there's an upcoming CartoDB Drupal module too. The best description I found so far: "CartoDB is an open source geospatial database platform that provides an SQL API layer. It allows developers to make querys to a cloud PostrgreSQL + OpenGIS database optimized to geospatial purposes. As a web service API, it is not required a certain database management system."

Open Alternatives to Google Maps

Lately there was a not much surprising news about Google products and services. Among other things Google has changed the Google Maps API use policy and will charge to those users that exceed some download limits.

It is well known that Google Maps is one of the most (or the most) famous mapping service used around the net and it starts the web GIS revolution some years ago but hopefully it is not the only API we can use. Bing and the discontinued Yahoo Maps, are great competitors but there are great and open alternatives to use.

I wrote this post to summarize the most important JavaScript API alternatives to Google Maps.

[Editor's note: this anonymous submission mainly discusses OpenLayers, Polymaps and Leaflet]
