@aliquot?ÿ You're kind of sidetracked. The use of the word Fraud is a different subject. What are you a lawyer?
@holy-cow So your saying FIRM maps aren't accurate to 0.4 feet?????
@bill93?ÿ I agree with you. My client has pictures of the 2011 flood, highest on record. The County is using the bogus FEMA FIRM maps and NGS benchma...
@aliquot Well FEMA is open about their map accuracy. NGS is mum about their benchmark accuracy. Evidently someone is training local government folks t...
@holy-cow The benchmarks shown on the old FIRM maps are NAVD27 vintage and have to be converted (which NGS has a nifty conversion program to do so on ...
@bill93 well there are no benchmarks shown on NAVD88 FIRM maps available to me.
@aliquot?ÿ Call it what you want. Deception, incompetence, stupidity. You tell a Government employee he or she is guilty of Fraud. They listen up. Yo...
@david-livingstone?ÿ From what I've experienced I feel pretty uneasy using a NGS benchmark.
ryancj31 ?ÿ What are you using for a Base unit elevation to compare into an NGS benchmark to within "hundredths"? I've certainly never seen that usin...
The FIRM maps don't reference what basis was used for their elevations. To use the benchmarks they would have had to identify the NGS benchmarks someh...
@stephen-ward I may have to get an R12. ?ÿ
@fairbanksls The County is requiring Elevation Certificate on property shown in the Flood areas by the FEMA FIRM maps. If your below the BFE you can'...
I guess Trimble listened to us grip about the feature not being reliable in the R10's. Do you still have to go through the calibration routines?
@oldpacer I use them at full resolution. They have improved so much the clarity is amazing. My CAD program degrades the clarity somewhat, but they are...
@holy-cow DOT benchmarks are way worse than NGS benchmarks. From what I know now I would never question anybody else's elevations. It depends on what...
@oldpacer Why is NGS begging Surveyors to GPS the NGS benchmarks and submit OPUS results for the new datum. Is OPUS another NGS scam? OPUS solutions ...
@fairbanksls They don't show benchmarks on the FIRM maps anymore. They did on the old NAD27 based maps, bu5t not on the relatively new NAVD88 FIRM ma...
NAVD88. They are in Floodway zoned A for the Log house and Zone AE for the garage. The Log Cabin owner had a Flood Plain Analysis done to the tune of ...
That's basically the process I use with my CAD program, but I have to have a point established to georeference it and there's a little rotation differ...
The Police have a lot of sources of information that you don't. They check Pawn shops regularly for stolen stuff. Get ahold of them for sure. You sure...
