Installing The Tiger Geocoder This is a customized version of Steve Frost's tiger geocoder revisions. This version includes a loader that is portable between Linux and Windows but loads a full state of data at a time. The loader helper tables and functions are prefixed with loader and stored in the tiger schema. If you only want to load a county, revise the wget call that is generated for the state to just download the statewide and specific counties or just download them by hand. The loader will only process files that exist. If you are on windows, you will need 7zip and wget. 7zip you can get from http://www.7-zip.org/ and wget you can get from http://gnuwin32.sourceforge.net/packages/wget.htm Tiger Geocoder is now part of the PostGIS documentation for further details about function use, refer to: http://postgis.net/docs/manual-dev/Extras.html#Tiger_Geocoder Refer to http://postgis.net/docs/manual-dev/postgis_installation.html#install_tiger_geocoder_extension for installing, upgrading, and loading data from extensions. Note that installing by script approach is now deprecated, but covered in: http://postgis.net/docs/manual-dev/postgis_installation.html#install_tiger_geocoder Loading data: 1. Create a folder called gisdata on root of server or your local pc if you have a fast network connection to the server. This folder is where the tiger files will be downloaded to. 2. Create a folder called temp in the gisdata folder. This will be the folder where we extract the downloaded tiger data. 3. Run the following commands at psql or pgAdmin III query window to generate the script, replacing 'DC', 'RI' with list of states you want and save contents to a .bat or sh file in YOUR CURRENT DIRECTORY. This will generate CODE for each state and append it to the script. (IF YOU ARE AT A PSQL PROMPT, FIRST RUN "\a", "\t", AND "\o script.xxx". THIS WILL MAKE YOUR OUTPUT UNALIGNED AND REDIRECT IT TO script.xxx. WITHOUT "\a" and "\t", THE SCRIPT WILL HAVE EXTRA WHITESPACE AND POSSIBLY NON-SCRIPT CHARACTERS THAT CAUSE IT TO BREAK.) -- UNIX /LINUX USERS -- -- Note even if you want just specific states you need to -- do this step since 2015 county, state tables are available only at national level SELECT loader_generate_nation_script('sh'); -- After the nation load, generate a bash script suitable for Unix command lines -- for your desired states. SELECT loader_generate_script(ARRAY['DC','RI'], 'sh'); ONCE YOU GENERATE THIS SCRIPT, EDIT IT TO ADD "set -e -u" AT THE TOP; THIS SETTING WILL MAKE IT STOP ON ERROR OR UNITIALIZED VARIABLE AND MAKE IT EASIER TO DEBUG ANY PROBLEMS. THEN RUN THE SCRIPT AT THE COMMAND LINE, REDIRECTING STANDARD OUTPUT AND STANDARD ERROR TO USEFUL FILES. YOU MAY WANT TO RUN "tail -f " TO SEE THE STANDARD ERROR AS IT GETS WRITTEN. FOR EXAMPLE: $ sh foo.sh 1>out 2>err; tail -f err -- WINDOWS USERS -- --To generate a WINDOWS DOS script -- this will generate the script to download the national layers -- Note even if you want just specific states you need to -- do this step since 2011 county, state tables are available only at national level SELECT loader_generate_nation_script('windows'); -- this you do after the nation load and for states you want SELECT loader_generate_script(ARRAY['DC','RI'], 'windows'); If your script disappears without loading anything, most likely one of your path settings is wrong. To troubleshoot run the batch script by first opening up a commandline and executing the file. That will keep the window open for you to see the error. -- Next run the script to install any missing indexes -- SELECT install_missing_indexes(); Alternatively if you want to see what indexes will be created before you create them run the below and manually run the steps generated: SELECT missing_indexes_generate_script(); 9. Copy and paste the generated script into a .bat or .sh file and put in gisdata folder you created and then run it, OR IF YOU REDIRECTED THE OUTPUT TO A FILE WITH "\o" MOVE THAT FILE TO GISDATA. 10. Test out the geocoder run these queries -- To get the best rated answer -- -- this is generally faster SELECT g.rating, ST_X(geomout) As lon, ST_Y(geomout) As lat, (addy).* FROM geocode('1731 New Hampshire Avenue Northwest, Washington, DC 20010', 1) As g; --To get multiple answers if there is more than 1 SELECT g.rating, ST_X(geomout) As lon, ST_Y(geomout) As lat, (addy).* FROM geocode('1731 New Hampshire Avenue Northwest, Washington, DC 20010') As g;
