ArcPad 10 vector layers slow

EddieViljoen — Fri, 08 Jul 2011 13:04:58 GMT

Hi
After converting some of our applications from ArcPad 7 to ArcPad 10, we found that the loading of the vector layers have become really slow.

We use quite large polygon layers in some apps, in a high speed environment, and as the map have to redraw regularly this becomes a huge issue. (Wasn't an issue in ver 7.)

Anybody else having similar issues?

Eddie

Eddie,

Which version of ArcGIS Desktop are you using?
Are you checking out to AXF or shapefile?
Do you utilize domains?
Do you utilize relationship classes?
How many layers do you have in your map document?
What mobile device are you using?

We will need to try and narrow down where the issue may be coming from.

Hi there Tim

Which version of ArcGIS Desktop are you using? - ArcMap 10
Are you checking out to AXF or shapefile? - Shapefile
Do you utilize domains? - No
Do you utilize relationship classes? - No
How many layers do you have in your map document? - >15
What mobile device are you using? - HP Tablet PC with XP

We did not use spatial indexes on some of the layers previously (ver 7), but now in ver 10 we have to use it, otherwise the drawing is too slow. Problem now exists that if you use a spatial index, then the index gets re-built every time that an edit was done. It takes some time to re-built this index. So either way there is a speed issue.

Apologies for bumping an old thread, but I'm having the same issue with my spatial indexes constantly rebuilding every time I want to make an edit. Every shapefile has a spatial index. I deleted them from within ArcCatalog and then created them anew from within ArcPad, which didn't help.

I'm not sure what relationships or domains are / would do... any advice would be appreciated. Thank you.

I clipped as many features as I could out, which reduced the spatial index build time.

I eventually removed all spatial indexes for shapefiles. The map takes more time to draw when zoomed in and all features turn on, but at least doing this prevented arcpad from taking 1-5 minutes to build the indexes.
