  1. NGS Leveling Adjustment Course Module 4: Generating the files needed for loading • Course requirements: • VPN (for remote access) • UNIX emulator (e.g. PuTTY) • User profile with access to IDB and leveling menus • FileZilla to transfer files from UNIX to PC (and back)

  2. Outline • Output from adjustment • Generating HOW_GOOD.BMS • Generating HOW_GOOD.UID • Removing duplicate UIDs • File naming conventions • Files required for loading

  3. Output from adjustment • In your Results folder (in UNIX), you should have: • CONSTRAINTS.report • lines file • L****.r6adj files • L****.rpt files (*.rpt files generated in main project directory, menu_v, #10 – reptgen)

  4. Generating HOW_GOOD.BMS • Create one file that lists all the *.r6adj file names in your adjustment • In your results directory, type: ls *.r6adj > adjfiles (adjfiles is suggested: call this anything you want) • This is similar to your “lines” file in that it contains a list of file names (in this case, the *.r6adj file names) • Check successful listing using command wcadjfiles (the number of lines reported back to you should match the number of l-number files you are adjusting) –otherwise review file in vi Editor (vi adjfiles)

  5. Generating HOW_GOOD.BMS • Create the HOW_GOOD.BMS file • menu6 r6tohgr (#9)  adjfiles • <Enter> • Adjusted r6 FILES  HGR Estimates (YES) • SELECT YOUR ADJUSTMENT DATUM: 1) 88 NAVD • PROCESS ONE FILE (YES) • NAME OF FILE (adjfiles) • PROCESS THE FILE of… CONSTRAINTS (YES) • NAME of FILE (indicate name of CONSTRAINTS file and directions to its directory, e.g. ../CONSTRAINTS) • Q = Quit

  6. Generating HOW_GOOD.BMS • View HOW_GOOD.BMS (e.g. vi Editor) Ortho. Height (m) PIDs Lat/Longs Vert. Datum SE Grav ssn’s Designation SE Height (mm) Gravity “A” = Adjusted

  7. Assigning UIDs • View HOW_GOOD.BMS (e.g. vi Editor) • Once you have the HOW_GOOD.BMS, type the command UIDs (in same directory as HOW_GOOD.BMS) • This creates the HOW_GOOD.UID file • Inspect file in vi Editor, or use more command • You will also need to set the vertical order of the level lines: • set_vorder HOW_GOOD.UID • Note: this assumes all O/C are the same. If not, it is recommended to set up different folders for each O/C and repeat ALL the steps for each. • Finally, combine all HOW_GOOD.UIDs into one file for loading

  8. Combining all HOW_GOOD.UID files • Create one overall HOW_GOOD_XX.UID • (“XX” stands for State code, e.g. TX, AL, MS, etc.) • cat HOW_GOOD_11.UID >> HOW_GOOD_XX.UID • cat HOW_GOOD_12.UID >> HOW_GOOD_XX.UID • Etc. Need to check w/ Vasanthi regarding naming conventions – may require name of job rather than state.

  9. Check for duplicate PIDs • Export HOW_GOOD_XX.UID to Excel • Sort on PIDs, check for duplicate entries. • Eliminate duplicates • Have someone review results of adjustment before submitting to Vasanthi • Submit to Vasanthi (check for exactly which files are needed; she has her own file structure that we need to follow)
