We are working with the local Police department on an iOS and Android app which will have an embedded Google map showing crime data from the past month.
This map is generated via a .KMZ file exported from ArcGIS.
We created a set of custom .EMF icons for this map and the Crime Analyst at the Police Department imported them fine, but they are extremely small in the KMZ layer that gets added to the Google map.
It looks like the icons get saved to the .KMZ file as 16x16 .PNGs.
When the Crime Analyst increases the size of the icons in ArcGIS, it makes them pixelated and blurry.
I've also tried unarchiving the .KMZ file and inserting larger versions of the custom symbols into the folder and then zipping it up and converting it to a .KMZ file, but then the Google Map wouldn't display any of the custom symbols.
Is there a simple way to retain the original size of the imported custom icons or to increase their size without pixelating them?
We have the custom icons as .SVG, .PNG, .EMF, and as a custom icon font. Is it possible to use either the .SVG or the icon font as a custom marker in ArcGIS so that scaling will not be an issue?
Let me know if you need more information or to see some of the files. I don't know much about the Arc suite of software and am just the app developer, but I can get information from the Crime Analyst.
