Get old 6.0 Arc/Info Grid Import back into 10

In my mind, it will be very helpful, to get the old Arc/Info Grid (*.asc Data) Import function of GMS 6 back into GMS 10.x as it was very helpful with using the SRTM-Data as DEM.

As these are datsets with a lot of data, converting them to Scatterdata for use in GMS (e. g. calculations) is not possible, as it creates millions of data points that are not easy to use.

With the old 6.0 import functions you could choose the region you wanted and therefor reduced the imported scatter point a lot!!!

In the latest versions of GMS this type of data comes in as a raster. You can interpolate from the raster to other objects directly - there is no need to convert the raster to scatter points. Rasters are much more memory efficient, and faster to open and render. Is there a reason that you need to convert the raster to scatter points?

Sometimes we work with SRTM data as DEM for regional Groundwater models and these Datasets are very large (converting them to Scatter Points creates 36,000,000 points each).

As these SRTM data have sometimes errors, we have to change some Z-values, delete points and add other points or calculate the z-values. All this is only possible with scatter data and not with raster.
