Hi! As I said in a previous message, I use qgis to put together many geographic information sources prior to downloading the data as kmz to my mobile.
That's the reason I wrote a small script to generate kmz icons from a qgis-generated kml. That script is a "sed" script, meaning it has to be processed with the "sed" utility included in Linux. If you have a Windows version of qgis bundled with Msys (such as osgeo4win), you could probably execute it from the msys command line. Someone could try to adapt it to python, but I don't know how to make python scripts. Please note: Lines are long and they could be wrapped when sendind as email. I will use an empty line (two carriage returns) to mark new line. ----------------------------------------------------------------------------------------------------------------------------------- SCRIPT 1 ---- Generate icons from "name" field This script takes a qgis-generated kml file, and adds an icon (called "Cueva.png") to every feature with a name containing "Cueva" or "Sima", another icon (called ."Icnitas.png") to every feature with a name containing "icnita" or "Icnita", another icon (called "Fosil.png") to every feature with a name like "Fosil", "Fósil", "fosil" or "fósil", and another icon (called "Mina.png") to every feature with a name containing "Mina". The icons should be placed in a folder called "images", and zipped along with the modified kml file in a file with kmz extension. The script should be invoked like this: sed mykmlfile.kml -f kmzfromname.sed > newkmlfile.kml After that, you should use your preferred zip manager to zip together the files. I use this: 7z -a -tzip newkmlfile.kmz newkmlfilekml images/*.png but the syntax would be different if you use a different zip manager. ----kmziconfromname.sed------------------CUT HERE------------------------------------------ #!/bin/sed #Replace name tag with Cueva or cueva with icon and name tag /name>[^>]*[Cc]ueva/{;s/<name>/<icon><href>images\/Cueva.png<\/href><\/icon><name>/;}; #Replace name tag with Sima or sima with icon and name tag /name>[^>]*[Ss]ima/{;s/<name>/<icon><href>images\/Cueva.png<\/href><\/icon><name>/;}; #Replace name tag with Icnita or icnita with icon and name tag /name>[^>]*[Ii]cnita/{;s/<name>/<icon><href>images\/Icnitas.png<\/href><\/icon><name>/;} #Replace name tag with F?sil or f?sil (probably, fosil or fósil) with icon and name tag /name>[^>]*[Ff].sil/{;s/<name>/<icon><href>images\/Fosil.png<\/href><\/icon><name>/;} #Replace name tag with Mina or mina with icon and name tag /name>[^>]*[Mm]ina/{;s/<name>/<icon><href>images\/Mina.png<\/href><\/icon><name>/;} #Previous code for icons was a pseudocode.

In the previous sample, I used the name to detect the class of each feature, but my kml file has a field caled T006_006_C that stores the actual feature class. So I could use that field instead. But, in order to do that, I have to read the field inside the <ExtendedData> tag and, after that, put a new flag outside that tag. Doing that with SED is tricky, because SED uses to read one line at a time. We have to tell it to group the whole <ExtendedData> group in a single line. Please notice you should adapt this script to your needs, i.e., replace T006_006_C with the field name you want, add code to replace the <!---icon --> tags with your preferred icon, and so on. The usage would be again, sed mykmlfile.kml -f kmzfromfield.sed > newkmlfile.kml After that, you should use your preferred zip manager to zip together the files. I use this: 7z -a -tzip newkmlfile.kmz newkmlfilekml images/*.png but the syntax would be different if you use a different zip manager. ---kmziconfromfield.sed----------------------CUT HERE------------------------------------------------------ #!/usr/bin/sed #Example: how to make icon from field using SED #Replace T006_006_C with fieldname :a N #Do not put spaces after the backslash in the next line: s/\ / /g /\/ExtendedData/!ba s/\(<ExtendedData.*SimpleData name=.T006_006_C.>\)\([^<]*\)\(.*<\/ExtendedData>\)/\1\2\3<!-- Icon_For:\2 -->/ #Step 2: Replace <!-- Icon_For:\2 --> with code for icon (<Style><IconStyle... etc) (See script 1) #Now you have to change all categories with their icon #This is an example on how to change "Icon fror:Modelado K*" to the "Cueva.png" icon: s/<!-- Icon for:Modelado [Kk].*-->/<icon>Cueva.png<\/icon>/ #Now we change <Icon> pseudocode with real icon code. s!<icon>!<Style><IconStyle><scale>1.0</scale><Icon>!; s!</icon>!</Icon></IconStyle><LabelStyle><scale>1.0</scale></LabelStyle><LineStyle><width>1,0</width></LineStyle></Style>! #Last of all, we change the <Folder> tag with the <Document> Tag. #It gives a name for kml layer in oruxmaps. s!Folder>!Document>! --kmziconfromfield.sed----------------------END OF FILE-----------------------------------------------
