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:
Also in the surveying and field measurement and monitoring category, V1 mentions a Datalogger Web Services API.
Here's the recent open source and open data geonews in batch mode.
This is major news for anyone using DEM datasets. Here's about a new elevation dataset named Global Multi-resolution Terrain Elevation Data 2010 - GMTED2010. Here's the USGS report about GMTED2010 and the description and download site on USGS's EROS.
From the article: "The U.S. Geological Survey (USGS) and the National Geospatial-Intelligence Agency (NGA) have released an updated and more accurate global elevation model that pulls data from Digital Terrain Elevation Data (DTED®) from the Shuttle Radar Topography Mission (SRTM); Canadian elevation data; SPOT 5 Reference 3D data; data from NASA’s Ice, Cloud, and land Elevation Satellite (ICESat); and updated Antarctica and Greenland terrain models. This new elevation data called Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010), replaces the thirty year old GTOPO30 terrain model.
GMTED2010 is a suite of seven raster data products: minimum elevation, maximum elevation, mean elevation, median elevation, standard deviation of elevation, systematic subsample, and breakline emphasis. The spatial resolution of GMTED2010 ranges from 30, 15 and 7.5 arc-seconds (approximately 1 kilometer, 500 meters and 250 meters, respectively)."
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.
[Editor's note: this anonymous submission mainly discusses OpenLayers, Polymaps and Leaflet]
O'Reilly describes it as a tool that "enables users to archive, search and export their Twitter, Facebook and Google+ history — both posts and post replies. It also allows users to see their network activity, including new followers, and to map that information. Originally created by Gina Trapani, ThinkUp is free and open source, and will run on a user's own web server."
Here's how it's introduced on the official ThinkUp site: "ThinkUp is a free, open source web application that captures all your activity on social networks like Twitter, Facebook and Google+. With ThinkUp, you can store your social activity in a database that you control, making it easy to search, sort, analyze, publish and display activity from your network. All you need is a web server that can run a PHP application."
Installation and configuration will probably require at least 30 minutes and you need minimal knowledge to configure the web server. In other words, it's not a tool that anyone can set up. But it's certainly valuable to anyone interested in understanding, mining the data, and mapping your social network activities. In bonus, you get an archive of your data. For a version 1.0, ThinkUp already does a lot. Here's the 5-minutes video that explains what is ThinkUp.
Here's the recent geospatial open source and open data news.

In the open data category:
Via email I learned that the open source OSM2NetworkDataset version 1.1 is now available, it readies OpenStreetMap data for ArcGIS's Network Analyst extension.
From the announcement: "Version 1.1 now supports ArcGIS 10.0, as well as ArcGIS 9.3.1. New features include restrictions for tracktype, smoothness, surface, and maxwidth.
The Java application OSM2NetworkDataset converts OpenStreetMap (OSM) data so it can be used for network analyses in the ArcGIS extension Network Analyst. It is designed to generate transportation networks for any mode of transportation and any region. The generated networks are based on OSM attributes, such as restrictions, one-way roads, turn restrictions, point barriers, and maximum speed. The path can be chosen according to the shortest distance or the shortest time with user defined average speed settings."
While we mentioned it once before, it never got its full story, until now.
I haven't found much about it on the popular geoblogs, but I recently learned about the existence of Autodesk's free 123D 3D modeling software. It's at the 'beta 6' stage and available only for Windows. It clearly sounds like Google SketchUp competition from Autodesk. This reminds me of Project Butterfly, which got launched as AutoCAD WS, another free tool from Autodesk.
From the 123D about page: "123D is a free solid modeling software program based on the same Autodesk technology used by millions of designers and engineers worldwide. Not an engineer? No problem, with Autodesk 123D you can design precise and makeable objects using smart tools that let you start with simple shapes and then edit and then tweak them into more complex shapes."
Here's recent geospatial open source software releases. All minor but welcomed updates.
Here's the recent open source geospatial news in batch mode, which includes everything about FOSS4G 2011 on the geoblogs that we haven't mentioned yet.
