Thematic mapping

[Anonymous]

I have a question about thematic mapping... I work in the Survey dept, and
when a plat is done, the client likes to see colored maps, based on the
product that is going on each lot. When I define my parcel, the software
labels the lot with the appropriate lot number. This lot number is a block
which contains 4 attributes.. One of these attributes is edited by me (I add
the product definition). I would like to be able to produce this colored map
by quering this information out of that block.... Is this possible? And if
so, I can't seem to get it to work... I have asked this before, and wasn't
able to get any of the answers to work.... I have had someone write a VBA
program that will allow me to add the product information as I label the
lots, to automate the process somewhat.... There has got to be a faster way,
than having a tech spend a couple days hatching lots....

Thanks for the help!!

Hi Robert,

I am not sure if I have fully understood what exactly you wish to achieve. It
would perhaps be a lot more clearer if I had some sample data to work with. I
have created some custom routines to perform query tasks and sometimes oversome
or get around some issues that woudl be difficult with Map. If you can send some
sample data, I can check it out for you to see what it takes to do this.

Hi Robert,

This can be done. What you need to do is to create a polygon topology using
your lots as the polygons and the block as a centroid for each lot. You can
then create a thematic map that will show different hatch patterns according
to your product name.

This is a very simplified explanation of what you need to do, but once
you've done it once, you can automate the process for multiple maps. Let me
know if you want more details.

Cheers,
David Walsh

Robert,
If I understand your problem correctly, I think that the thematic query
option will definitly work for you. I use the thematic query to color fill
geologic maps routinely based on a geologic label. It doesn't matter to Map if
there are 2 or 2,000 polygons (i.e. parcels), the colors are filled in
automatically in a few seconds as solid hatching patterns. I use object data
definitions rather than blocks, but I believe you can use your block attributes
just as easily as I use object data to do the same thing. Since I teach a GIS
course, I have summarized the steps in making a geologic map with a thematic
query in the below document on my web site:

http://www.usouthal.edu/usa/geography/allison/gy461/1_24000GeoStand.pdf

Sections VI and V would probably be of most interest to you. If you have not
created a polygon topology, sections I through III will be important.

If you don't have any luck I wouldn't mind taking a look at your file. Sometimes
it's necessary to look at a specific situation,

Good Luck,
David
