Importing city map on MAP 3D

[boubami]

Dear,

I'd like to import a city MAP in MAP 3D with roads, buildinngs and others.

Whenever i did it, i only get the picture (in tiff format or PNG...format) of my map that i cannot use.

I'd like to create an electrical network on it with details.

Can you help me do this please.

Aboubacar,
Your Tif file won't be much use. It is raster, and you need vector--lines, polygons, etc.
You can check to see if any local government has shapefiles. I usually start my search for GIS data >>>Here<<<.

You can try using this source:

Click DOWNLOAD LAYER then select ZIPPED SHAPEFILE.

Extract the zip file. Once you have the shapefile you have two options:

1. Connect to the shapefile using the DATA CONNECT palette. Bring in the shapefile as a feature data object (FDO).
2. Use MAPIMPORT command. This command will 'convert' the shapefile into AutoCAD polylines.

Like all shapefiles, this shapefile is georeferenced to LL84 (WGS84 datum). or EPSG 4326. Before exercising one of the two options above, make use you assign an appropriate coordinate system to modelspace. The CS you assign to modelspace does NOT have to be LL84, it can be UTM84-30N (EPSG 32630) or any other applicable coordinate system for your target city.

The shapefile downloaded shows main roads. If you wish to obtain a shapefile with more detail, main roads as well as secondary roads, then you'll need to search for other downloadable 'vectors' such as those formatted in shp, gdb, or dwg. You do NOT want to download RASTER images such as tiff, jpeg, or png.

Aboubacar,
And >>>Here<<< is another source that even has powerlines and buildings. Unfortunately it costs money.

Hi @boubami ,

the previously mentioned resources are very good places to get data, does that answer your question?

Alternatively, if you search for free available 3D data you might also try to use Infraworks Model Builder.

But unfortunately, this will need another installation of a program - so just an idea.

Hello,

I'd like to work in a specific area: Ouagadougou/Burkina Faso.

How can I create the map of Ouagadougou?

Open a new, clean metric template and follow the steps below. This new template should not have an assigned coordinate system.

1.  MAPCSASSIGN on command line. Search for UTM84. Scroll down and select UTM84-30N, click ASSIGN button.
2. Go to Geolocation Tab=>Online Map Panel=>Map Button=>Select Bing Hybrid. The Bing Logo will appear in lower right corner of modelspace. The logo indicates you have successfully 'connected' to Bing online imagery.
3. Using your mouse, zoom-out and pan until you see the Red Geomarker. (The geomarker indicates a coordinate system has been assigned to modelspace--Map3D doesn't ascertain whether the assign CS is appropriate, it merely indicates that a CS has been assigned.)

Image-3.

You may now use your mouse to zoom-in and pan to Ouagadougou, Burkina Faso. At this point, you may, if you wish, turn off Bing Hybrid. 

You can now perform the following functions:

• Zoom in/out or pan around the city of Ouagadougou.
• Connect to Feature Data Objects (FDO) such as shapefiles
• Connect to or insert georeferenced images
• Convert from GIS entities to AutoCAD entities such as points, lines and polygons
• Draw new AutoCAD entities and convert the AutoCAD entities into GIS shapefiles
• Edit shapefiles
• Other functions that I can't remember

Special Note Regarding Coordinate Systems of Feature Data Objects:

Even if Feature Data Objects are not using UTM84-30N, they will still be positioned accurately when you bring them into modelspace. Your Map3D  program will accurately transform from the FDO's native coordinate system to the coordinate system you have assigned to modelspace. This means when connecting to a shapefile (or raster) referenced against WGS84 Lat/Long degrees, they will still be geospatially accurate against your drawing, even when your drawing has the assigned CS UTM84-30N.
