Hi all,

I have create some territories on a map, i would like to now how many square kilometers that territory is. is this possible in Mappoint 2006
(territory is a collection of postalcodes).

kind regards

Ludo

You can iterate through the territory dataset and get each postal code contained within a particular territory. Then you can use ActiveMap.Datasets.GetDemographics() to query for the area (sqkm) of each postal code. Add them up to get the total sqkm for each territory.

Hi,

Thanks for your reply Paul, I am not that experienced with MapPoint, I have tried to retrieve the data, but no succes...
here is the code:
Imports MapPoint
Imports MapPoint.GeoMapRegion
PublicClass Form1
Dim objapp As MapPoint.Application
Dim objDataSet As MapPoint.DataSet
Dim objDataMap As MapPoint.DataMap
Dim objField As MapPoint.Field
Dim objMap As MapPoint.Map
Dim objLocation As MapPoint.Location
Dim objShape As MapPoint.Shape
PrivateSub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) HandlesMyBase.Load
Dim km AsString
'Create Mappoint as Object and allow control
objapp = CreateObject("Mappoint.application")
objapp.Visible = True
objapp.UserControl = True
km = Getkm("77600")
EndSub
Function Getkm(ByVal Postcode AsString)
'Add data to current map
objDataSet = objapp.ActiveMap.DataSets.GetDemographics(GeoCount ry.geoCountryFrance)
objField = objDataSet.Fields(1)
objDataMap = objDataSet.DisplayDataMap(GeoDataMapType.geoDataMa pTypeShadedArea, objField, GeoShowDataBy.geoShowByPostal1, , , , 15)
'Find and set location
objMap = objapp.ActiveMap
objLocation = objMap.FindResults(Postcode).Item(1)
'get data ???
Getkm =
EndFunction

I don't now what i do wrong to get the specific data..

kind regards

It may not be what you’re looking for but you can do this fairly easily in excel vba (or Access) by handling the data-bases independent of MP. I worked through an example in which I set up an excel workbook with sheet “Territories Definition” containing the ‘export to excel’ data from the MP territories map, sheet “Territory Names” containing a column with the territory names and sheet “Demographics” containing the area information. To get this area information use Data Mapping Wizard to plot a shaded map for all of France showing postcode areas. Now export that data to excel (5942 postcode areas in total) and cut and paste into your main excel workbook. You can now do the analysis independent of MP and get around the vagaries of the query methods on MP. If you set up another sheet called “Analysis” then my following feeble attempt at code would, I think, give you the area for a specified territory

Code:

Private Sub GetTerritoryArea_Click()

  Dim TerritoryName As String, Postcode As String
  Dim nCurrentRow As Integer, nRow1 As Integer, nRow2 As Integer, _ 
                iCount As Integer, jCount As Integer
  Dim R As Range
  Dim Area As Single, TotalArea As Single

  nCurrentRow = 2
  Worksheets("Territory Definition").Cells(1, 4).Value = "Area"

  Do While Worksheets("Territory Definition").Cells(nCurrentRow, 1) <> ""
     Postcode = Worksheets("Territory Definition").Cells(nCurrentRow, 1).Value
     Set R = Worksheets("Demographics").Range("A1:C5943").Find(Postcode)
     If Not R Is Nothing Then Area = R.Offset(0, 2).Value
     Worksheets("Territory Definition").Cells(nCurrentRow, 4).Value = Area
     Set R = Nothing
     nCurrentRow = nCurrentRow + 1
  Loop

  TerritoryName = InputBox("Which Territory?")

  nCurrentRow = 2
  TotalArea = 0#
  Do While Worksheets("Territory Definition").Cells(nCurrentRow, 1) <> ""
       If Worksheets("Territory Definition").Cells(nCurrentRow, 3).Value = TerritoryName _
       Then TotalArea = TotalArea + Worksheets("Territory Definition"). _
       Cells(nCurrentRow, 4).Value

  nCurrentRow = nCurrentRow + 1
  Loop

  MsgBox "Area of " & TerritoryName & " is " & TotalArea

End Sub

If you wanted to output the area of ALL your territories to the “Analysis” sheet you could substitute the following code into the routine above

Code:

  nRow1 = Worksheets("Territory Names").Cells(1, 1).End(xlDown).Row 
  nRow2 = Worksheets("Territory Definition").Cells(1, 1).End(xlDown).Row
  iCount = 2
    For iCount = 2 To nRow1
    jCount = 2
    TotalArea = 0#
       For jCount = 2 To nRow2
       If Worksheets("Territory Definition").Cells(jCount, 3).Value _
       = Worksheets("Territory    Names").Cells(iCount, 1).Value Then _
       TotalArea = TotalArea + Worksheets("Territory Definition").Cells(jCount, 4).Value
      Next jCount
   Worksheets("Analysis").Cells(iCount, 1).Value = _
           Worksheets("Territory Names").Cells(iCount, 1).Value
   Worksheets("Analysis").Cells(iCount, 2).Value = TotalArea
   Next iCount

Taking this approach you only need to set up the French demographic database once and it can contain lots of columns, including your own data, that can be accessed by the off-set attribute in Find. Also you can you can use the territory map to redefine territories and then cut and paste the results into “Territory Definitions” and generate the new results

Code:

Private Sub TerritoryMap_Click()

  Dim objApp As MapPoint.Application
  Dim objMap As MapPoint.Map
  Dim objDataSet1 As MapPoint.DataSet
  Dim objDataSets As MapPoint.DataSets
  Dim zDataSource1 As String

  Set objApp = CreateObject("mappoint.application") ' Start Mappoint Europe 2006
  Set objMap = objapp.ActiveMap 
  objApp.Visible = True
  objApp.UserControl = True

  Set objDataSets = objapp.ActiveMap.DataSets
  zDataSource1 = "…… \FranceTerritories.xls!Territory Definition!"
  Set objDataSet1 = objDataSets.ImportTerritories(zDataSource1, , geoCountryFrance, , geoImportExcelSheet)
    objMap.DataSets.ZoomTo 

End Sub

HTH. I'm not a programmer so please treat the code with care if you use any of it. It'll need checking!!
