Best raster format to use. using a laptop with arcpad

[noamrozenfeld]

Hi,
We work with an old and slow powered Trimble devices (GeoXT 2008), and because that I need the survey teams to work with a lot of data, we use a laptop with arcpad 10 installed on it, and use the trimble device, with the arcpad installed on it as well, to use only as a GPS device to pin-point on the laptop, where the survey team is.
Because of varios reason, i clip raster as the background imagery for the survey team, as well.

What i found out, was that the fastest way, for arcpad to display the raster is exporting the clipped area (in ArcMap) as an ECW and than, on the Get data for ArcPad toolbar, exporting it as JPG2000.
I've tried directly exporting as JPG2000 from ArcMap, but it works very slow on the laptop, and also the Tiff and JPG formats.

Does that sound reasonable?
Is there any other way you would suggest me, which is faster?

If you're still here :confused: - does it make sense that the Trimble GeoXT 2008 can't carry an area of 10 sq km with about 8 background layers full of data and 5 empty layers that the survey team update?

Hola noam,

I would suggest when working with aerial(s) within your project, especially on a laptop/toughbook. Check out all your vector data from within ArcMap, with which ever Action(s) you desire but don't check out your aerial imagery. Simply once you have checked out your vector data, open your .apm and then add in the aerial imagery in its native format. This will not only give you the best performance for your project, but also the aerial imagery will draw much faster. I am including the documentation for all supported raster format, from within ArcPad. I hope this helps and answers your questions, we are here to assist. Gracias, noam!

Hi,
Thanks for the reply.
But, i've tried to export my ecw's to jpg, or jpg2000 and upload it on the laptop manually, after openning an .apm containning only the vector data.
But it was SLOW going on the laptop.

My initial process is using ecw's and converting them to another format using global mapper, like jpg2000, because the files i usually
use are ecw's and require the alteration (because ecw is not a supported format).
Maybe something in that process?

Thanks,
Noam
