Strategies

Identification

1. Look for "invisible text" (adjust brightness / contrast / colors / levels / threshold / curves)

Searching

1. Look for groups of businesses
   1. sometimes gas stations can change names, so use ["amenity"="fuel"]
2. Use substract to remove known false matches

Example Query Snippets

Find Harbors

nwr["seamark:type"="harbour"];

Split Countries by driving_side:

Left

area["driving_side"="left"]["admin_level"="2"]->.leftSideDriving;

Right

area["driving_side"="right"]["admin_level"="2"]->.rightSideDriving;

Exclude locations by id

nwr(area.texas)["healthcare"="pharmacy"]["name"~"cvs",i]->.allCVS;
(
  nwr.allCVS;
  -
  nwr(id:8292180749,384562084,92086146);
)->.filteredCVS;

Find Clusters of bridges

Finds bridges within 2000m of eachother

nwr["bridge"]["highway"]->.allBridges;

(
  nwr.allBridges;
  nwr.allBridges(around:2000);
)->.clusteredBridges;
