GeoREST has just received its first major release. GeoREST is a framework based on existing open source libraries such as MapGuide and FDO that is intended to allow the publication and interaction of geospatial web resources in a RESTful manner. GeoREST is distributed under the Lesser GPL license.
GeoREST 1.0 enables the dynamic publication of KML, GeoRSS, etc; search engines to crawl you geospatial data, and web form updates to search/update your data. Further information and the latest download can be found on the GeoRest Project Pages.

The Google Maps Data API is a web service that allows client applications to view, store, and update map data for Google Maps, using the Google Data API. Data is stored in the form of individual features and collections of features. Full pricing information has yet to be released, but the service is currently free for publically-visible data. |

Over the weekend, v1.7.0 of the popular GDAL/OGR library was released. Although technically not a geo-web product, GDAL/OGR is used by a number of popular geo-web tools such as UMN MapServer. We also used a tool from the beta of this version in our recent Polar Maps and Projections article. as well as the usual bug fixes and minor changes, GDAL/OGR 1.7 adds support for a number of less-common raster formats ( BAG, EPSILON,
Northwood/VerticalMapper, R, Rasterlite, SAGA GIS Binary, SRP
(USRP/ASRP), EarthWatch .TIL, WKT Raster ); support for a number of vector formats (DXF, GeoRSS, GTM, PCIDSK, VFK); significant improvements to existing raster & vector drivers ( GeoRaster, GeoTIFF, HFA, JPEG2000 JasPer, JPEG2000 Kakadu, NITF, CSV, KML, SQLite/SpataiLite, VRT); support for Python 3; and the new gdaldem and gdalbuildvrt utilities. Further information and downloads can be found on the OSGeo website, here.

This article was previously published on GeoChalkboard, and has been reproduced here with permission. GeoChalkboard is published by Geospatial Training Services who provide a range of geospatial web courses.
With the ArcGIS Server Query Task you can perform attribute and spatial queries against data layers in a map service that has been exposed. You can also combine these query types to perform a combination attribute and spatial query. Some examples would perhaps be illustrative at this point. An attribute query might search for all land parcels with a valuation of greater than $100,000. A spatial query could be used to find all land parcels that intersect a 100 year floodplain, and a combination query might search for all land parcels with a valuation of greater than $100,000 and whose geometry intersects the 100 year floodplain. In this article we’ll take a look at the mechanics of querying data from a map service using the ArcGIS Server JavaScript API.
