for raster image ,it is difficult to conduct this kind of operation
you can convert the raster file into vector format
and select polygons which area is smaller than cartographic minimum unit
and use the eliminate tools, which can be found in the toolbox
Hello everyone,
my question is similar to http://forums.esri.com/thread.asp?t=194817&f=983&c=93
select a random sample of points out of an existing point feature layer. Also, to minimize spatial autocorrelation, I would like to specify a minimum distance between points.
All hints would be highly appreciated!
Thanks
interesting question.
i have a idea,
you can convert the pdf file into CDR, which is the format of Coreldraw and output its vector file,such as dwg
then ,you can translate the dwg into commoal gis file using gis software, maybe arcgis,
however ,the coordinate system and the topo relation must be rebuilt.
good luck.
you can get it from sarscape help,
Orbit file
This file – if available – is intended to enter precise orbital information. In case it is not available the "leader file" must be entered. This file is mandatory.
Leader file
File name of the original leader data (prefix "LED" for JAXA products; suffix "ldr" for ERSDAC products). This file is mandatory.
Data_1 to Data_4 file
File name of the original PALSAR RAW data. Depending on the data provider, the following data structure can be found:
- JAXA products - The number of data files (prefix "IMG") may vary from 1 (single polarization) to 4 (full polarization).
- ERSDAC products - One data file (suffix "raw"), which contains 1 or more polarizations, is provided.
When dual or full polarization JAXA products are used, it is suggested to enter the HH polarization as Data_1 file; this is because the Doppler Centroid is better estimated in the HH polarization.
These files are mandatory.
Output file
Output file name of the focused data. In case of multi-polarization data, a suffix corresponding to the specific polarization is added to the name of each output file. This file is mandatory.
