geomap – A new, open-source JavaScript mapping API

More than ever, users expect to interact with maps on the Internet. Developers need lightweight and capable ways to integrate interactive maps with their websites.

Applied Geographics has been solving web mapping problems for over six years. In this time, we have created solutions for displaying geographic data from different servers simultaneously, allowing users to interact with that data comfortably and giving developers ways to streamline their code.

Cellular Automata Quantum GIS plugin and web-based application

Cellular Automata (CA) models are increasingly applied in the environmental studies due to their dynamic nature, spatial explicity, and compatibility with the raster format widely used in GIS. We present here a CA Quantum GIS plugin, coupled with a web-based spatial decision support tool (using GeoExt). The application addresses the expansion of invasive species and is developed using open-source geospatial tools. We will describe the CA QGIS plugin as well as the technical issues of the...

Raster support is the new big feature of PostGIS 2.0. You can now store georeferenced, multiband, multiresolution, with nodata value raster coverages in the popular spatial database. A raster coverage is typically stored as a table of many tiles. You can load rasters in any format supported by GDAL and the list of raster tables is available to applications in a table named raster_columns. You can do raster/vector analysis doing intersections as you are used to do them with vector data stored...

PAGC: Geocoding -- Recent Advances and Future Developments

The Postal Address Geocoder (or PAGC) is an open source library and web service framework for geocoding locations based on either postal addresses, street intersections, or landmarks. The system offers a number of features that differentiate it from other open source geocoding software solutions:

  • PAGC is written in ANSI C it runs on all major operating systems, and can be easily ported to nearly all operating systems
  • PAGC is pre-configured to use data from several...

Beyond vectors: Adapting remote sensing research for environmental monitoring with open source hardware and software: Citizen mapping the BP oil spill with balloons and kites

Grassroots Mapping (, an online network of participatory, community-based mapping projects, was established in early 2010, just prior to the BP Gulf of Mexico disaster. In response to the spill, the grassroots mapping community worked with the Louisiana Bucket Brigade, a New Orleans based non-profit, to carry out volunteer mapping trips to affected areas of the Gulf Coast. Using low cost kites and balloons with consumer point and shoot cameras attached, volunteers with...

A Prototype of open source tool for water resources management in developing countries

The development of almost all socio-economic sectors depends on water resources. Indeed, water resources are mobilized to satisfy various uses like domestic, agricultural, industrial, livestock, tourism, leisure etc. In developing countries, water resources are not available in sufficient quantity and quality anytime, anywhere. This situation is worsened by the pressure induced by socioeconomic and population growth. It's therefore necessary to create the conditions for sustainable access to...

Tutorial: User Friendly Web Processing Services (WPS)-No programming needed


Spatial Data Infrastructures have evolved from concepts to reality in the last decade. However, they are still focused on data retrieval and visualization. To proceed in the direction of a true Spatial Information Infrastructure, it is evident to take the processing of geodata into account. The OGC Web Processing Service Interface (WPS) is the most promising standard to address geoprocessing in a standardized manner. Several free and open-source WPS implementations exist....

Scaling PostGIS Queries with Stado

Stado, formerly know as GridSQL, provides a powerful and flexible analytical environment allowing users to process large amounts of data using a shared-nothing, massively parallel processing (MPP) architecture with PostgreSQL and PostGIS. Data is automatically partitioned across multiple nodes and each node processes its subset of data allowing queries to be distributed across the cluster and run in parallel. This fully open source architecture allows database performance to scale linearly...

Speed up your GIS server - run GIS software on solid-state drives (SSD)

Solid-State Drives (SSDs) are recently becoming popular storage mediums in laptops, and are praised for their speed and shock resistance. However, there has been some debate over whether or not SSDs are ready for the data center.

GIS software is known for its high demands on server hardware. Especially hard-drives became a bottleneck when serving map tiles, rendering map images or running spatial computations. SSDs seem to be one possibility to increase IO performance, but optimized...

Numerical models, such as hydrodynamic and climate models, produce output with a large number of variables and a large number of grid cells and time steps. Further use of the resulting data products has been challenging, especially for further use outside the institute of origin. Due to the vastness of the data, simply downloading copies of data is impossible. Web services are therefore used to access subsets of the data. The most mature candidates for working with gridded data are...

Geoprocessing with Neo4j Spatial and OSM

What better way to perform geoprocessing than on a graph! And what better dataset to play with than Open Street Map!

Since we presented Neo4j Spatial at FOSS4G last year, our support for geoprocessing functions and for modeling, editing and visualization of OSM data has improved considerably. We will discuss the advantages of using a graph database for geographic data and geoprocessing, and we will demonstrate this using the amazing Open Street Map data model.

Tuning GDAL Raster Performance

Web mapping performance is often constrained by the speed of access to the underlying geospatial data. A comparison of different file formats, image organization techniques, compression, caching and other factors will be discussed in the context of their impact on performance for raster data access intensive applications. Results will be presented for the particular case of web mapping with MapServer on top of the GDAL raster data access library.
