I have recently published a new spatial dataset, the PRIO-GRID. Primarily the dataset is targeting researchers working with armed conflict. However, the data are also useful for other types of research involving spatial data. The PRIO-Grid data set is a spatio-temporal grid structure constructed to aid the compilation, management and analysis of spatial data within [...]

Happy PostGIS day everyone! Until about year ago, most of my work involved using proprietary GIS software, most of it ArcGIS. Today, almost 100 % of the work i do involve open-source software. Contributing much to this shift has without a doubt been PostGIS. One of my main projects the last year have been the [...]

Many within the GIS community working on global data are familiar with the Gridded Population of the World (GPW). This global gridded population estimate has now been more available through a web-service. This lets the user zoom around to investigate the data without having to download the rasterdata. Additionally and more interesting are the population [...]

A new report from CIESIN and the Austrian Insitute of Technology has released an global assessment on light pollution on protected areas. The analysis is done to reveal how light pollution affects protected areas. Hence, two new variables was created from combining the global protected area distribution data and nighttime lights data: a Protected Area [...]

Within the next couple of days, gisintersect will publish its first special issue article on GIS in Peace and Conflict Research. Stay tuned!

The Geospatial Modelling Environment (GME) is the predecessor of the Hawths Tools extension for ArcGIS. It is designed to facilitate rigorous spatial analysis and modelling by linking ArcGIS to the statistical software package R. The new software has increased graphic ability in addition to batch processing, and records the workflow to ease replication. One additional [...]

FME or “Feature Manipulation Engine”, is a spatial ETL (extract, transform and load) engine, that supports over 250 formats. The new 2010 desktop version of the software includes new powerful transformers, which are able to do various geoprocess your data. The neat part with FME is the ability to make complex models (something like ArcGIS [...]

As a result of many new features, new interface and additional changes in the structure of ArcGIS, the ArcGIS 9.4 will be released as ArcGIS 10/X. GISintersect visited an ESRI conference, and can provide some additional updates on the functionality. ArcMap 10 will be able to host a ArcCatalog window, easing your access to your [...]
