Introduction<\/h2>\n

In a recent blog<\/a>, we covered querying geospatial data with manual bounding boxes. In this blog, we’ll take the same dataset\/query but perform the query using GeoHashes<\/a> instead.<\/p>\n

GeoHashes are alpha numeric encodings of areas on earth. The more bits in the encoding, the more precise the area is prescribing. A 1-digit long Geohash covers approximately 2500km while an 8-digit long Geohash covers approximately 20m. For example, the 9q geohash covers most of California and the Western United States while San Francisco \/ San Jose bay area is spread over several geohashes, 9qb, 9qc, 9q8, and 9q9.<\/p>\n

\"\"<\/a><\/p>\n

Geohashes are easily vizualized with several different tools such as this<\/a>.<\/p>\n

Java spatial4j GeoHashUtils<\/h2>\n

The ingest portion of our Geospatial app uses Java to read a New York Open Data’s Crime Complaint CSV file and load it into to GridDB. While there are several Geohash implementations for Java, we chose to demonstrate spatial4j’s GeoHashUtils<\/a> as it appears to be the most popular with the largest developer community. The modifications to the previous Ingest tool are simple, instead of manipulating the latitude and longitude into a container name, we’ll use a 6-digit Geohash:<\/p>\n

\n
String cName = \"geo_\"+GeohashUtils.encodeLatLon(c.Latitude, c.Longitude, 6);<\/code><\/pre>\n<\/div>\n
A GEOHASH column is also added to the colum schema where a full 12-digit geohash is stored.<\/p>\n
\n
c.GEOHASH=GeohashUtils.encodeLatLon(c.Latitude, c.Longitude);<\/code><\/pre>\n<\/div>\n
Querying with Python and Proximity Hashes<\/h2>\n
There are many libraries that implement\/utilize geohashes to allow developers to implement more featureful applications. One of these is Proximityhash<\/code> which builds a list of geohashes that cover a circle around the provided point with the given radius. Proximityhash accepts a precision argument as well, denoting how many digits of a geohash should be created as well as a compression argument where it return fewer, less precise geohashes if they are completely within the radius of the search point.<\/p>\n
\"\"<\/a><\/p>\n
Using Proximityhash, we’ll now query the data we just loaded, first by getting a list of 6-digit geohashes to figure out which containers to query and then a list of geohashes that we’ll query in each container.<\/p>\n
\n
radius_hashes = proximityhash.create_geohash(lat, lon, distance, 8, georaptor_flag=True).split(',')\ncontainer_hashes = proximityhash.create_geohash(lat, lon, distance, 6, georaptor_flag=False).split(',')<\/code><\/pre>\n<\/div>\n
Now iterate through all of the containers building a TQL statement: SELECT * where geohash LIKE 'XXXXXXXX%' or geohash LIKE 'YYYYYYYY%' ...<\/code>.<\/p>\n
There is some query optimization as well, only geohashes that are within the queried container are added to the TQL statement.<\/p>\n
\n
retval=[]\nfor container in container_hashes:\n\n    ts = gridstore.get_container(\"geo_\"+container)\n    tql = \"SELECT * WHERE \"\n    orstmt=\"\"\n    for geohash in radius_hashes:\n        if geohash.startswith(container):\n            tql = tql + orstmt + \"geohash LIKE '\"+geohash+\"%'\"\n            orstmt=\" OR \"\n\n    if orstmt != \"\":\n        try:\n            query = ts.query(tql) \n            rs = query.fetch(False) \n\n            while rs.has_next():\n                data = rs.next()\n                retval.append(data)\n        except:\n            pass<\/code><\/pre>\n<\/div>\n
Performance<\/h2>\n
We compared the performance of querying with varying precision geohashes against the manual bounding box method from our previous blog on geospatial querying.<\/p>\n\n\n\n\n\n\n\n\n
Description<\/th>\nNumber of Geohashes<\/th>\nDuration (Seconds)<\/th>\n<\/tr>\n<\/thead>\n
Manual Bounding Box<\/td>\n<\/td>\n0.005<\/td>\n<\/tr>\n
7-digit Geohash<\/td>\n59<\/td>\n0.007<\/td>\n<\/tr>\n
8-digit Geohash<\/td>\n1522<\/td>\n0.15<\/td>\n<\/tr>\n
8-digit Compressed Geohash<\/td>\n468<\/td>\n0.030<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
With similar levels of precision, Geohashing is only slightly slower.<\/p>\n
Conclusion<\/h2>\n
Geohashing is an easy implement method to use for querying geospatial data that does not require manual manipulation of data with minimal performance loss compared to other methods.
