[Qgis-developer] Application of QGIS to

[Tom Maddock]

Hello, 

We are newcomers to QGIS and are trying to evaluate its suitability for
application to some ecological programs we have developed.  I am not sure we
are in the proper forum for our questions, which are many, but here is a
start.

 

We have developed an ArcGIS 9.2 custom application in VB 2005, .NET
framework 2.0 to derive parameters for the riparian evapotranspiration
package in MODFLOW and visualize MODFLOW groundwater results. We are
considering using QGIS to perform the geo-processing component of our
program instead of using the ESRI product.  It should be noted that MODFLOW
is a FORTRAN-90 product (yes, some people still use FORTRAN), and is used to
solve the groundwater flow equations.

 

We would like to know if QGIS provides some of the out of the box
geo-processing components such as overlay analysis and zonal statistics
similar to ArcGIS.

 

Here is the list of geo-processing tasks that we perform in our program:

 

*	Attributing vegetation polygon shapefile interactively by selecting
polygons and enter % cover values on a form

 

*	Creating finite difference grid as a polygon shapefile in order to
support irregular grid sizes

 

*	Intersecting vegetation polygon shapefile with the finite difference
grid shapefile and updating areas of the polygons

 

*	Obtaining average surface elevation per riparian polygon derived
from (DEM) and write it to vegetation polygon shapefile

 

*	Access each record in the attribute table and write values in a text
file with specific format.

 

Couple of questions:

 

*	Is there a support for relational database management such as join
and relates?

 

*	What are the supporting programming languages and can we re-use some
of the components that are already written in VB .NET in the project?
