acadmap2pgsql

The program is an intersection of Autodesk Map to the PostgreSQL/PostGIS database management system. The function of the program is to convert all geometrical information and the combined object data into SQL-commands and to issue a pgsql-dump.

libLAS

libLAS is a C/C++ library for reading and writing the very common LAS LiDAR format. The ASPRS LAS format is a sequential binary format used to store data from LiDAR sensors and by LiDAR processing software for data interchange and archival.

LiDAR (Light Detection and Ranging) is a form of high precision range detection much like a radar system that uses laser light as the electromagnetic emission. One of LiDAR systems’ products is a “point cloud” data product that can be conceptualized as a series of point measurements representing distance from the sensor to a returned emission. A common storage format for these point cloud data is ASPRS LAS format.

OpenEV

OpenEV is a software library and application for viewing and analysing raster and vector geospatial data.

OpenEV is used by private companies, universities, governments and non-profit organizations around the world. OpenEV is both:

• An application for displaying and analysing geospatial data
• A developer library from creating new applications

PostGIS

Geometry Engine - Open Source ( GEOS )

GEOS (Geometry Engine - Open Source) is a C++ port of the  Java Topology Suite (JTS). As such, it aims to contain the complete functionality of JTS in C++. This includes all the  OpenGIS Simple Features for SQL spatial predicate functions and spatial operators, as well as specific JTS enhanced topology functions.

Feature Data Objects ( FDO )

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.

MetaCRS

MetaCRS is a project encompassing several projections, and coordinate system related technologies. Our plan is to treat a variety of coordinate system activities as one Project from an OSGeo point of view. This helps provide enough "project mass" to justify the full OSGeo project treatment. But more importantly it would give us a forum to cooperate. Sharing things like coordinate system dictionaries, test suites and mathematical formulations.

GeoTools

GeoTools is an open source (LGPL) Java code library which provides standards compliant methods for the manipulation of geospatial data, for example to implement Geographic Information Systems (GIS). The GeoTools library implements Open Geospatial Consortium (OGC) specifications as they are developed.

GDAL/OGR

Geospatial Data Abstraction Library (GDAL/OGR) is a cross platform C++ translator library for raster and vector geospatial data formats that is released under an X/MIT style Open Source license by the Open Source Geospatial Foundation. As a library, it presents a single abstract data model to the calling application for all supported formats. It also comes with a variety of useful commandline utilities for data translation and processing.
