Creating Regular points every meter at a county level. Is this possible?

Question

I have a need to create regular points with a coordinate every meter in a county. I've tried several methods including Hawthes Tools in ArcMap9.3, ET GeoWizards, and the standard Toolbox. I have encountered reoccurring instances where all of the processes have froze up.I am assuming that these programs can't handle that data generation. I tried this in QGIS as well. I need help ASAP.

Answer 1

Try this:

1. Convert your county polygons to raster using the ArcGIS Conversion Toolbox > To Raster > Polygon to Raster. Set the cell size to 1m.
2. Use spatial analyst's Sample Tool (Spatial Analyst toolbox > Extraction tools > sample) to create points for every cell.
3. Extract only the points that intersect your county polygon.

If you continue to run into problems, try splitting the county polygon into smaller areas and using this same process.

Answer 2

Personally, I would get the grid of the MBR of the country: create a 2D array based on the min max coords of the MBR, working how many items would fill in that grid with 1 meter intervals and then loop[ through, creating points on the fly, rounding it off with a delete outside of the county.

So you'll know the Min / Max X, so you'll know how many metres will fill in that grid, so you have your grid of X values. Do the same for the Y and you have that grid.

The following is pseudo code

for y in range(0, rows):
    for x in range(0, cols):
        currentPoint = (y, x) 
        CreatePoint

I reckon that's about 20 lines of python with the erase outside?
