Re: Intensity Heat map?

Hi,

 

>> I know esri software can do it, but they charge for each module and it gets pretty expensive

You have to pay extra for a simple thematic mapping functionality? No, that is built in .... the functionality, not the data.

And why do I mention the data here? Because I asked now 3 times how your data is structured, you don't give an answer (to an important question ... a question we need answered to give you function-names or specific workflows for how you can go on with your work), but call me "to get pissy".

 

Find attached a video that shows how to load data, how to create formulas so you see how to get a value for "items per any property" (what you can use for your heat-values) and as the last step how to configure the mapping to display these values in colored-shades. The video is German (sorry, I only have the German Map3D), but you see the icons I use and that is equal to the Map3D in English or other languages.

(sorry that the 1.5MB upload-limit does not allow a better video resolution)

Yes Map3D can do what you need. Depending on what information you have and the format it's in as to how to theme it. Do you have dumb autocad objects with text, shp files, microstation dng files, PostGIS database or what? There is a few different ways to get the results you want depending on the data.

thanks again murph, thats good news to hear that it has that functionality At this time i have an esri shape file and the table data is in excel but i could easily put it in an access (.mdb) database if that would help.

If you have the shp files still in the orginal format (.shp, .shx & .dbf ) then you can use the data connect and theme as shown in Alfred's zip file video. Connect to the shp instead of SQL Lite and set the style(theme) by values in the data table. If you only want two colors then look at using the Less than < and Greater than > in the expression for setting the theme.

Hi,

 

I follow this discussion, and another question appears to me linked to data, and I haven't found solution.

If I've well understood there are 2 shp files : 1 for polygon corresponding to area (in the town) and 1 ponctual for fire call.

How is it possible to count the number of ponctuel inside an area and transfer this information to area data?

 

I 've tried with Gis overlay (identity), so I can add id of area on each ponctual object, but I don't know how to transfer / fill a column with the number of fire call inside a area. 

 

Thanks

If

 

Table "A"                                              &      Table "B"

 

FID Polygon Area#                                       Area#    FireCount (FireCount is the total per Area#, not one individual fire)

 

 

You can join the data tables (B To A) Option, create a join  or RC in the data table window or in the Display manager, rc the data, create a join and then apply your style

 

What do(es) your data table(s) have for columns of data?

Thanks, but sorry I don't undestand what is your process.

 

I join a SDF file with a class ZONE with 4 polygons and a classe FIRE with some points. In each areas, I've 3 or 4 or 5 or 8 points.

I just want to count how many point per area (and add this number as info) to each polygon. The goal is to do a thematic map on polygons according number of point are inside each polygon.

 

Thanks

I fear you can't in Autodesk environment, while in the free Qgis it would be easy as 1-2-3, sir.

Hi,

 

>> I fear you can't in Autodesk environment

If you have a point theme and a polygon theme you can overlay them (e.g. using "Identity"), the result is a new theme having assigned the polygon-id to the point. Using any database with SQL-ability you can create a new view or table holding the polygon-id + the count of the point-objects ==> link that back to the polygon theme and that's it.

But yes, you need to know SQL for this step (SELECT COUNT ... GROUP BY ,,,).
