What is WebDMAP?
The Web-based Disease Mapping and Analysis Program (WebDMAP) is a web-based Geographic Information System (GIS) software designed to generate smoothed, continuous maps of crude or age-adjusted disease rates. WebDMAP provides advanced spatial analysis, GIS, and visualization methods in an easy-to-use, web-based analysis system designed specifically for users with little experience in spatial analysis methods or GIS software. WebDMAP is built using free, open-source products and is available as free, open-source software.
How do I install WebDMAP?
There are two options for installing WebDMAP:
- As a standalone server application on a dedicated Linux machine, or
- As a virtual appliance that runs on your computer.
Installing WebDMAP on a dedicated server
If you would like to deploy WebDMAP on a dedicated server, please follow the instructions provided in the server installation document. The installation manual assumes that you are using CentOS 6.0, although the procedure will also work with any other Linux distributions. Please send me an email to get access to the latest code repository.
Installing the WebDMAP Virtual Machine
WebDMAP can also be installed as a VirtualBox virtual machine. The virtual machine can be downloaded from here. See the virtual machine installation document for instructions. The documentation provides instructions for two common network scenarios:
- You plan to use WebDMAP on a network over which you have control – for example, a home network where you add another device to the network easily. See this installation video for more details on configuring the virtual machine.
- You plan to use WebDMAP on a network over which you do not have control – for example, a University lab environment where you cannot add another device to the network. See this installation video for more details on configuring the virtual machine.
The WebDMAP Virtual Machine is the easiest way to get started with the software.
Using the VM in “Host-Only” mode as outlined in the installation video disables network access – in this setup, you will not get any notification emails from WebDMAP.
- Direct age-adjustment algorithm modified to use expected counts of disease as the basis for defining the spatial filter definitions
- Direct age-sex adjustment was added as a separate module.
- The user interface has been redesigned with context-sensitive help.
- The VM supports self-signed certificates for secure data transmission.
- Drop down menus can be used to select existing filter definitions.
- The previous version required this information from the user.
- An option to delete tables from an existing project has been added under the Project Maintenance tab. This allows users to recover projects that contain temporary tables.
- A single configuration file holds all the parameters needed to deploy WebDMAP. Previous versions required users to manually change every file.
- Minor bug fixes.
- WebDMAP 4.0 adds enhanced visualization capabilities to WebDMAP 3.0. Disease maps created using WebDMAP can now be visualized using a web browser.
- Continuous patterns of disease burdens are automatically overlaid on top of satellite and road network data obtained from a variety of online map data providers including Google, Yahoo and Microsoft Live Maps.
- WebDMAP 3 has been completely rewritten in PHP and provides an easier user interface along with major changes to the way in which users and output data locations are managed.
WebDMAP v2 that was written in Perl will no longer be supported. Please note that the database functions have not changed between v2 and v3.
