Debian GIS Workstation packages

OpenCPN is a concise ship-borne GUI chart plotter application supporting:

* GPS/GPDS Postition Input
* BSB Raster Chart Display
* S57 Vector ENChart Display
* AIS Input Decoding
* Waypoint Autopilot Navigation

One location on the globe, in any coordinate system. Geo::Point tries to hide the maths and the coordinate system in which the point is represented.

One of the most confusing things when handling geometrical data, is that sometimes latlong, sometimes xy are used: horizontal and vertical organization reversed. This package tries to hide this from your program by providing abstract accessors latlong(), longlat(), xy(), and yx().

This package provides the following modules:

• Geo::Line - a sequence of connected points
• Geo::Point - a point on the globe
• Geo::Proj - simplified wrapper for Geo::Proj4
• Geo::Shape - base class for 2-dimensional points on the earth surface
• Geo::Space - A collection of various items
• Geo::Surface - A surface description

Geo::Proj4 is a wrapper library around PROJ, a cartographic projection library, for easy use in Perl software.

The Open Source PROJ library converts between geographic coordinate systems. It is able to convert between geodetic latitude and longitude (LL, most commonly the WGS84 projection), into an enormous variety of other cartographic projections (XY, usually UTM).

This C library supports TIFF 6.0 based interchange format for georeferenced raster imagery. The GeoTIFF standard has been developed for reading, and writing geographic meta-information tags on top of TIFF raster.

This package contains EPSG Geodetic Paramenters data files which can be used with standard projections. These data are useful to better dump geo-contents of many GeoTIFF files.

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. LiDAR (Light Detection and Ranging) is an optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant target. The prevalent method to determine distance to an object or surface is to use laser pulses.

This package contains the essential toolset to manage LiDAR data: lasinfo, lasmerge, las2las, las2txt, txt2las, las2ogr.

osgEarth is a scalable terrain rendering toolkit for OpenSceneGraph (OSG), an open source, high performance, 3D graphics toolkit. Just create a simple XML file, point it at your imagery, elevation, and vector data, load it into your favorite OSG application, and go! osgEarth supports all kinds of data and comes with lots of examples to help you get up and running quickly and easily.

This package contains binaries.

pprepair (planar partition repair) takes a set of polygons and ensures that they form a valid planar partition, made of valid polygons and having no gaps or overlaps. It can be used as a validator, telling of problems in individual polygons or in the planar partition, and also as an automatic repair tool, outputting a set of polygons that do form a valid planar partition.

prepair permits you to easily repair "broken" GIS polygons, and that according to the international standards ISO 19107. In brief, given a polygon stored in WKT, it automatically repairs it and gives you back a valid WKT. Automated repair methods can be considered as interpreting ambiguous or ill-defined polygons and giving a coherent and clearly defined output.

pyspatialite is an interface to the SQLite 3.x embedded relational database engine with spatialite extensions.

It is almost fully compliant with the Python database API version 2.0 and also exposes the unique features of SQLite and spatialite.

This package contains the pyspatialite module for Python 2.

Thuban can read geographic data in the shapefile format. Main features of thuban are the layer management and the possibility to navigate on the map, to control the visual appearance of objects, to identify and edit attributes by object selection and to print and export the resulting maps for further processing.

This package contains the thuban program and its libraries.

The goal of VTP is to foster the creation of tools for easily constructing any part of the real world in interactive, 3D digital form.

This goal will require a synergetic convergence of the fields of CAD, GIS, visual simulation, surveying and remote sensing. VTP gathers information and tracks progress in areas such as procedural scene construction, feature extraction, and rendering algorithms. VTP writes and supports a set of software tools, including an interactive runtime environment (VTP Enviro). The tools and their source code are freely shared to help accelerate the adoption and development of the necessary technologies.

Capaware! is conceived as a system of 3D terrain representation with multilayer representation of diverse types of resources capabilities and executed applications integration feature.

With OpenSceneGraph as the graphical engine, Capaware! enables the creation and modification of new layers of data through access to remote servers where they are. Moreover, the system can be completed with new features and programmed executables through the use of specific plugins. In this way we can gradually increase the power of the final system.
