几个开源GIS库的更新

最主要的还是Proj 4.7.0 支持EPSG:3857，这就基本上否定了我们惯用的EPSG:900913的用法，或者是两者在同一时间并存。其次pyWPS也是值得关注，这个库越来越成熟了。对于做基于服务器端的空间分析是个好消息。

PROJ 4.7.0 Library Released

PROJ.4, the major cartographic projections library used by so many geospatial software has released version 4.7.0. From the GFOSS blog: “Important is the regeneration of the “nad/epsg” init file with EPSG 7.1 database which now includes support for the Google Mercator (EPSG:3857). Furthermore, a substantial acceleration in some application environments is gained through a new cache implementation and and various thread safety improvements could be implemented.”

Shapely 1.0.14 released

This release fixes a bug in writing out WKB on 64-bit systems. It was solved by a MapFish user. If you are one, or are writing WKB to PostGIS or another application, an upgrade is recommended. I’ve uploaded an sdist tohttp://pypi.python.org/pypi/Shapely/1.0.14.

libLAS 1.2.1 Released

The open source ASPRS LiDAR data translation toolset named libLAS has released version 1.2.1. From the main site: “libLAS is a C/C++ library for reading and writing ASPRS LAS versions 1.0, 1.1 and 1.2 data. The LAS format is a sequential binary format used to store data from sensors and as intermediate processing storage by some LiDAR-related applications.”

PyWPS Quick Guide & Shapely 1.0.13

On the Python geospatial theme, the Linfiniti Geo blog shares a A quick quide to getting up and running with PyWPS. A quick reminder: WPS stands for Web Processing Service (WPS) and is an OGC standard. From the introduction: “PyWPS is a great project by Jachym Cepicky and Intevation to provide an open (Open Source and Open Standards) implementation of the OGC Web Processing Service spec. In this article, I will give a quick run through of getting up and running enough to have the obligatory “Hello World” service running.” There’s also the news of the release of Shapely 1.0.13, also using Python.
