Map workflow - separate files for specific area

Situation: ca 7000 tiled raster files in one folder but only a subset for a specific area is required, SHP file containing tiles and filenames and SHP file with area of interest available

raster tiles (green), area of interest (blue)

workflow:

1 - load both SHP files into Map
2 - spatial query to select tiles for area of interest

raster tiles for area of interest

3 - export attribute data for selection

shp with tiles (selection for area of interest) - export attribute data (filenames) 

4 - open attribute data in Excel
5 - extract exact filename with Excel and add addtional parameters (DOS commands), as result you need something like this: 

... copy 6895_2595_r3x.tif c:\temp\dom copy 6895_2600_r3x.tif c:\temp\dom copy 6895_2605_r3x.tif c:\temp\dom ...

further processing in Excel

6 - copy result into new textfile, save as BAT file into folder with raster files and execute



What happens if you do not have a SHP file containg tiles and filenames?

This might be an option to create one with Map:

- load raster files into Map (command: _mapiinsert), choose option to show frame only (do not load thousands of raster files, only let Map display the frames)

_mapiinsert - show frames only

- add AutoCAD layer with image frames to DisplayManager (query current drawing)

- add a label to the newly add layer, choose ".IMAGENAME" as label text

label added to iamge frames - path to file is used as text

- export as SHP (command: _mapexport), export option "Text" : you will get a Point SHP with text insertion points as points and label text as attribute

- use point shape for spatial query

DWG export - lineweight missing

When exporting to CAD drawing (maptoacad, editable, with template) some polylines got the default lineweight of "0" although the Map display model assigns certain lineweights to them. In Map these lines displayed correctly. For the polylines affected the lineweight was set using an expression:

<Override>
 <SymbolName>LTYP20</SymbolName>
 <ParameterIdentifier>LINEWEIGHT</ParameterIdentifier>
 <ParameterValue>0.35 * 500</ParameterValue>
</Override>

To get the lineweight exported correctly one has to put the expression in brackets:

<Override>
 <SymbolName>LTYP20</SymbolName>
 <ParameterIdentifier>LINEWEIGHT</ParameterIdentifier>
 <ParameterValue>(0.35 * 500)</ParameterValue>
</Override>

DWG Export - Linienstärke fehlt

In der exportierten DWG (_maptoacad, Bearbeitbar, mit Vorlage) hatten einige Linien die Linienstärke "0", obwohl im Darstellungsmodell ein anderer Wert eingestellt ist. In Map wird die Linienstärke auch korrekt dargestellt. Bei den betroffenen Linien war im Map-Layer die Linienstärke über einen Ausdruck festgelegt:

<Override>
 <SymbolName>LTYP20</SymbolName>
 <ParameterIdentifier>LINEWEIGHT</ParameterIdentifier>
 <ParameterValue>0.35 * 500</ParameterValue>
</Override>

Für den DWG Export lag die Lösung darin, den Ausdruck in Klammern zu setzen:

<Override>
 <SymbolName>LTYP20</SymbolName>
 <ParameterIdentifier>LINEWEIGHT</ParameterIdentifier>
 <ParameterValue>(0.35 * 500)</ParameterValue>
</Override>
