ETL for pe_anp_sernanp

######### # GDSC ETL is performed in two steps: shell script to ETL data into postgres # and then additional transformations with SQL in postGIS (if needed). #### ######### # Step 1 - bash script (pseudo code) #### # create directory structure and move into it mkdir -p /data/pe_anp_sernanp/{download,etl} && cd /data/pe_anp_sernanp # set update flag based on last update and update frequency do_update=0 if date() < last_update + update_frequency else do_update = 1 # download if update flag is set: if do_update == 1 then ogr2ogr -nln pe_anp_sernanp download/pe_anp_sernanp.json 'https://geoservidorperu.minam.gob.pe/arcgis/rest/services/ServicioANP/MapServer/6/query?outFields=*&where=1%3D1&outSR=4326&f=geojson' # replace column names Shape__Length and Shape__Area to avoid conflict when # providing as service on ArcServer. sed -i 's/Shape__Length/shape_length/gI; s/Shape__Area/shape_area/gI' download/pe_anp_sernanp.json # load into postGIS with: ogr2ogr -lco GEOMETRY_NAME=geom -f PostgreSQL PG:"" download/pe_anp_sernanp.json -nlt multipolygon -nln pe_anp_sernanp ######### # Step 2 - SQL script (pseudo code): #### # remove duplicate points and make geometries valid:UPDATE pe_anp_sernanp SET geom=ST_MakeValid(ST_RemoveRepeatedPoints(geom));# add local geometry column and reproject existing geometries into local EPSG: SELECT AddGeometryColumn ( 'pe_anp_sernanp', 'geom_local', 5387, 'multipolygon', 2 ); UPDATE pe_anp_sernanp SET geom_local=ST_MakeValid(ST_RemoveRepeatedPoints(ST_Transform(ST_Multi(geom), 5387))); CREATE INDEX pe_anp_sernanp_geom_local_idx ON pe_anp_sernanp USING GIST (geom_local); NOTIFY pgrst, 'reload schema';"
