Discussion: Tools for splitting up field checking work across several people

Hi, all:
Our small GPHXO club is in need of a major map revision for an upcoming meet in Feb '18. Most of the volunteers for field checking have little or no mapping experience. I was hoping that someone has a methodology that is based on using a GPS phone app, so that the volunteers can track exactly where they are on the base map.

Specifically, has anyone any experience with a phone app that meets the following criteria:
a. Cheap ($10 - $15)
b. versions for Android and IOS
c. works with downloaded maps (no network connection)
d. Can georeference and display a map file that is exportable from OCAD 8 or OOM
e. Allows recording/naming/exporting GPS waypoints

Any recommendations? Also, if any club has documented instructions for how they distribute field checking work, I'd love to see it.

Thanks!

Open Orienteering Mapper (free) has an Android version, but not iOS (and likely never will sure to license issues for open source software on iOS). But phones are a bit small for this, tablets better.

I used Back Country Navigator (Android only, free version adequate) to capture GPS tracks and waypoints of power line pilons, and then imported them later into the map, but that requires going back to tweak the track and locations, so doing it all in mapping software may be better. Or not. My experiences have been mixed, though I'll be using advice from a clubmate when I next try; he had enough success to keep doing it.

I think I may have answered my own question--I've been looking around, and I think I have a process that will work OK, al least for Android:

1. Export the base map file as a jpg from OCAD
2. Use (free) QGIS software to georeference the jpg map and generate a Geotiff file
3. Use MapC2MapC software (costs 15 pounds, but you can do proof-of-concept with demo version) to create a file and "zoom tiles" that are compatible with Locus Map Pro software
4. Buy Locus Map Pro ($7.49), install on tablets or phones, and load the map files into the Locus/maps directory

It seems like it will do the job that I want it to do, and cheaper than OCAD11. I also tried to create custom map files for Backcountry Navigator, but haven't gotten it working, and will probably just stick to Locus Map

For fieldchecking, I carry a handheld GPS on which waypoints are recorded while walking the park. Waypoints are simply named #1, #2 ,#3, etc. A description of each waypoint is recorded on the back of the map or in the margin. At home, the waypoints are plotted on the screen with your favorite GPS utility. The screen capture can be used as a template in OCAD or OOM. The list of waypoints should include some known points that are prominent on the map.

I export kmz raster from Ocad 10 and load it to Custom Maps (Android)

I have used "Custom Maps" on an Android phone. You can georeference an image of your O-map so the GPS points to your location on the map, but it doesn't allow marking points or saving locations.

Thanks for the input. I think I'm getting closer to where I want to be. The Avenza Maps app is supported on Android/IOS/W10 and the free download allows import of a custom GeoTiff map. So...I can easily create a georeferenced map in QGIS, save a GeoTiff, and I'm done! I have yet to try the app in the field, but unless it's really cumbersone, this might be the free, generic tool that I'm looking for...

I'd like to add another vote for Custom Maps! I use it both when fieldchecking and every time I place control flags for events, and I've hosted 9 events so far this year.
