If you haven't tried this one out yet, I highly recommend you do.
This program allows you to download geo-referenced PDF files to your smart-phone. It will then show your position on the PDF.
Being able to see your position on a USGS quad, quad index, Township-Range-Section index, ect. is very helpful in the field. I have used it several times to walk directly to a stone mound section corner.
Even more helpful is when you geo-reference a survey plat to the publically available aerial imagery and see your position on the record of survey while you are performing recon. for corners, setting up traverse, or cost estimates.
I can imagine it would be extremely helpful for the rodman to be able to see the subdivision layout when they are staking so they know what direction to start walking.
The office crew can send you an assessor's map showing adjacent land owner information via. e-mail. Not only can you view the map, but you can see your position and orientation.
Very fun stuff.
I haven't tried that app, but a client just told me about "igis" for iphone.
You can upload geo-referenced shape files and view your superimposed position in the field. I asked if you could upload remotely (via 4g) and his answer was you need Wi-Fi. Not sure; may just be a file size issue.
I'm going to try it out as soon as he cuts loose something in the 100-Acre range (been sitting idle for about 5 years).
I'm not good with geo-referencing pdf's (autocad doesn't play well with pdf's in my experience). So the shape file capability is more appealing.
Brave new world.
ps> For the price some guys are doing work around here, I think they are pin-setting with their phones 😛 .
You can download the USGS 24K maps via. 3G in the field.
With PDF Maps, you can also overlay .kml/.kmz files.
So I convert shape files to .kml files and view them on the PDF.
Avenza, and GeoPDF's are great. We have been using them for over a year now, and clients will ask for this as a service for us to generate maps in Arcmap. Export the geo PDFs with maps showing imagery/quads with access roads labeled, and project key points. Works great with ipads when navigating to key points, or to find out how lost you really are!
Could you tell me what projection you are using for the georeferenced PDF maps please?
I've exported maps as PDF from ArcMap with the include georeferencing box ticked but they always show in Avenza as map not referenced so I've a feeling that it Avenza may be a bit picky about the projection.
I've tried WGS84 but without success so any advice welcome.
