Conefor – Habitat areas and links for the maintenance or improvement of connectivity

January 21, 2018

Conefor is a software package that allows quantifying the importance of habitat areas and links for the maintenance or improvement of connectivity, as well as evaluating the impacts on connectivity of habitat and landscape changes. Conefor is conceived as a tool for spatial ecology analyses and for decision-making support in conservation planning, through the identification and prioritization of critical sites for habitat and landscape connectivity. Previous versions of Conefor were known as Conefor Sensinode.

Graphab – Ecological networks from the framework of graph theory

January 21, 2018

Land cover changes resulting from urban sprawl, transport network intensification and agricultural changes contribute to fragment wildlife habitats and may lead to question viability of animal and vegetal populations. Including issues of ecological networks and landscape connectivity in spatial planning and land management proves therefore to be a crucial stake for preserving biodiversity. In this context, the modelling of ecological networks is a suitable approach for achieving diagnoses, prioritizing action to be done (for instance ecological restoration) and comparing prospective scenarios of development or conservation. This kind of modelling is complementary to approaches led by field specialists in ecology.

Graphab software is devoted to the modelling of ecological networks from the framework of graph theory. It is the only tool able to include construction and visualization of graphs, connectivity analyses and links with external data. It is easily compatible with Geographical Information Systems.

The QgisODK plugin allows to build a “on field” mobile survey in few minutes starting from a Qgis layer and get back collected data with the help of Open Data Kit tools and services.
Open Data Kit (ODK) is a free and open-source set of tools which help to manage mobile data collection solutions.

The typical ODK collection workflow is based on the following activities:

  • survey form design (XlsForm/XForm)
  • deployment of survey forms on ODK collect Android App
  • on field data collection by a mobile device
  • data aggregation on server

postgisQueryBuilder

January 15, 2018

The postgisQueryBuilder QGis plugin is aimed to to provide a friendly environment to perform spatial analysis in postgresql/postgis without having to deal with SQL code. It is not intented to replace the Qgis built-in DBManager that have a wide usage that covers all aspects of Qgis/Postgis interaction. It can be used in educational environments for a live analysis of the structure of the common spatial queries. Furthermore, The plugin can manage postgresql views and can be used for deploying spatial analysis frameworks based on chains of spatial relations.

HistOsm – Historical places

HistOSM is a WebGIS application to visually explore historic objects stored in the OpenStreetMap database. Your visual exploration process is supported by dynamically created statistics showing the top most used object categories in the current map view extent. The diagram itself can be used to filter the objects on the map to a specific value by clicking on a category.

Kartograph

January 10, 2018

Kartograph is a simple and lightweight framework for building interactive map applications without Google Maps or any other mapping service. It was created with the needs of designers and data journalists in mind.

Actually, Kartograph is two libraries. One generates beautiful & compact SVG maps; the other helps you to create interactive maps that run across all major browsers.

NCAR’s Community Climate System Model (CCSM3) was one of the global climate model included in the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC). NCAR’s GIS program provides GIS-compatible user access to CCSM3 AR4 global (1.4 degree or ~155 km) and downscaled (4.5 km) continental U.S. simulations. Follow the links below to access data as shapefiles, textfiles, KML files, WMS, WCS or download a map.
