The Google Maps' Street View service plays catch-up and implements a "PhotoSynth-like" service. This allows a user to navigate through a Street View panorama with geo-located photographs supplied by other users. The images have been active for a while but the navigation has only just been made public and was announced on Friday in the Google blog post, Navigate your way through user photos in Street View. The new service is not a fully functional PhotoSynth service so you cannot jump between StreetView and an independent geo-located PhotoSynth (ie. photo assembly). Still, it works well with the panoramas in Google Maps' Street View service, and its operation is very smooth. Most of the blog discussion concentrates on the fact that the main difference is that this uses Flash, and Bing Maps/PhotoSynth uses Silverlight which limits its accessibility on Linux systems. However I think the advantages/disadvantages might be opposite to the current online opinion. Silverlight is supported on Windows and Intel Mac systems. Take up is only 50% but that is after only about 18 months of Silverlight 2 and it is growing fast. It is supported on Linux systems using Moonlight although I do not know if Moonlight supports Bing Maps, and whether many Linux users would actually install it (those expressing an opinion on discussion blogs are usually declining Moonlight on ideological and not technological grounds). There is also the argument that desktop Linux is set to remain a tiny minority of installed systems for the foreseeable future. In contrast, Apple has a well-known dislike of Flash and many of their new systems (eg. the iPad) do not support it. Although Flash is a popular choice for new web mapping systems, there is a growing feeling that its days are numbered. |

GIS Cloud has just entered its public beta phase. GIS Cloud is an online "GIS for the web". The 'cloud' in the name refers to it being SaaS (Software-as-a-Service). It is unclear if it is implemented in true 'cloud' fashion (eg. like Amazon EC2 or Microsoft's Azure). Unlike the vast bulk of the "geo-web" systems we cover, this is much more than a simple map viewer/annotator/query engine; but allows more GIS-like data operations. |

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.

MetaCarta have released Geotagger for the Red Hat Linux Enterprise environment.This is described as an 'unbundling' as it was previously only available as a part of MetaCarta's Geographic Search and Referencing Platform. Geotagger attempts to tag words and phrases in natural language text with their geographic position - something generally much more sophisticated than traditional geocoding.
The press release can be found here. |

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.
