I did this to create common names I followed the following steps.. 1. convert lines to centroids using the polypoint tool in GME(I used GME to keep the point on the line and I did this to get better joins with the road centreline) 2. Spatial join with suburbs 3. Spatial Join with Road centrelines 4. Attribute join with the source data 5. Claculate field (PipeMaterial & "_" & Year(DateConstructed) & "_" & RoadName & "_" & Suburbname) End Result (CICL_1970_Smith Str_Jacksontown) its not perfect but we then have about 1/5 the amount of records to review when looking at breaks per meter and other values such as this.. ...

I just had the same thing happen.. It turned out the dataframe took its reference froma  background shapefile I added to arcmap first.. re made the mxd with the Checkout GPS data 1st and it was fine 🙂 ... View more

jsanborn20's method is great! before this could be done... I had this happen a few times and found a way to save the data meaning I didn't have to drive out and recapture the data. What happened was: 1. Checking AXF and SSF hung after 90 mins so I hit cancel. 2. Once successfully cancelled I restarted ArcMap and tried again 3. this time ArcMap wouldn't allow check in as it indicated 0 new features�?�(oh #$$%% I've deleted the data off the logger already.) 4. Insert 99 extra step of messing around with access and the ArcGIS MDB and other files. 5. Eventually I downloaded SQL Server Management Studio Express(limited free use) to edit the contents of the axf file http://www.microsoft.com/downloads/details.aspx?familyid=6053C6F8-82C8-479C-B25B-9ACA13141C9E&displaylang=en 6. Connect to the AXF as such.. 6. after playing around with an AXF for a while I found that AXF_STATUS field was what I was after. Using:     select * from GPSSMAINTENANCEHOLE 7. I set this the AXF_STATUS field to 1 by using the query bellow: (NB you will see some checked out data as well is null so the query has the option of " Where AXF_Status=16777217") UPDATE GPSSMAINTENANCEHOLE SET AXF_STATUS=1 Where AXF_Status=16777217 Hoorah!! Now you can check the file in again! ... View more

Back in the days of me being a GPS salesman.... we tested Juno vs nomad and found that the juno allways had better results.. and a Trimble rep informed us that TDS put the GPS chip on the nomad under the power button(close to your body and hand!) where the juno has its chip top and centre under the Trimble m. the test we used was to map car park lines in and out of cover at the same time to get as close as possible to the same ephemeris results... ...

I don't know how well this Australian based method will work in the US. I haven't had to do this for lines and polygons.... I created a TIN of my local geoid. It was fairly easy as its just an ascii XYZ file. in arcmap(arcinfo) I then subtract that height from the point data to give accurite local heights ... View more

For our Rehabilitation of watermains, Gravity / Pressure Sewermains / Sewer manholes we added the following fields: · RehabMethod(Sliplined, Swagelining, PipeBurst, Spraylining, Spirally Wound, Fold and Form, CIPP, Patchlininig) · RehabHostPipeMaterial(Domain: Pipematerial) · RehabHostConstructionDate(date) Any further info would be in the AMS. So some examples are attached as a graphic(I'm lazy!) ... View more

I use 2 different ways.. 1 easy.. intersect and then disolve (assuming the attributes will disolve the overlaps...) or the anoying one I allways end up resorting to USe Unions to output complete dataset with the overlaps. copy to a personal GDB close arcmap open the PGDB in access add a field called DeleteMe. create a "Create table" query using totals and group by the ShapeAreaNew: round([shape_area[,4) make sure you have the Unique ID in this query(eg object ID) and select oone of first/last/max/min. create the new table create a new "Update" query and joint the new table with the GIS table using the UniqueID(eg obkjectID) showing all records from the GIS table(this is a outer or inner join) make this query update the DeleteMe field to "Not Meeeee" where there is a relationship based on existing in the other table. then back to arcmap select by location: based on the intersection output to highlight ALL of the overlaping polygons ONLY! select by attributes on delete me to remove from selection "Not Meeeee" Done! Hacked up eh.. it usulay takes me about 10 minutes to do this and I"ve done it a fair few times... ... View more

This could be magnetic interferance. these are very vaunerable to nearby metal objects. this also needs to be considered in the calabration procedure.. the Trupulse website has a good video on calabration. another thing that ou should look into is your local magnetic declination (ie the difference between True(map) north and magnetic north. where I am(Near sydney Aust) it is +12.5. ...

that last post should work. I just couldn't find a windows mobile version of GNSS internet radio. the R8 with integrated Celluar board might do this a trick.. and justr set you minimum accuracy to .3m if you are chasing RTK fixed as a float is usualy around 700mm in your GPS preferences under quality. From arcpad help about EPE [INDENT]Maximum EPE This field is used in the same way as the one described above. When the second maximum check box is checked, a quality control is placed on the quality parameter selected. By default the Estimated Position Error (EPE) of incoming GPS positions is chosen for the second maximum value. The value in the box to the right specifies the maximum allowable EPE. The maximum allowable EPE you use should correspond directly to the maximum distance error you can accept. For example, if you can accept a maximum distance error of 15 meters, you should set the maximum allowable EPE to 15�??assuming your display units are set to metric on the Display tab of the ArcPad Options dialog box. EPE is only output by Garmin GPS receivers as part of a proprietary Garmin message, so this setting is only valid when using a Garmin GPS receiver. This affects you in the following ways: If the EPE of the current GPS position exceeds the maximum value while you are capturing a feature using the GPS, you will either get a warning message or not be allowed to capture data until the EPE is less than or equal to the maximum value, depending on whether Non-Compulsory Warnings or Compulsory Warnings is selected. If the Maximum EPE Exceeded check box on the Alerts tab is checked, an alert message and/or sound occurs whenever the EPE of the current GPS position exceeds the specified value. Other values that can chosen in place of PDOP are: HDOP, VDOP, TDOP, EPE, VPE, DAGE. The default is unchecked and no value is specified. [/INDENT] ... View more
