With 60,000 location-based POIs consistently checked by our POI team and field personnel, Mapa's GIS department is the leading POI provider in Israel. Accurately collected and continuously updated data on each POI, produces comprehensive information on the chosen areas of interest.
Each POI is designated by type (Italian restaurant, dental clinic, synagogue, etc.). Category codes are based on the U.S. Standard Industrial Classification (SIC). Each POI is described by at least one category, but one POI may also be described by several categories. Classification of POIs under a standard codes promotes efficient search of the relevant information, thus reducing the cost of integrating the POI database into customers' data systems and applications.
POI Location and navigation to a POI
In some cases additional information is provided that describes POI's navigation point. It can happen when for some reason there is a need for explicitly mention road segment that access POI. Navigation point mentioned is defined by the node id of appropriate road segment that have to be used to access the POI. Navigation point information includes x,y coordinates and reference to the road segment (by segment id) and junctions layer (by junction node id). Navigation point coordinates are usually different from POI centroid coordinates.
For every POI, composed of several buildings a single calculated central point is assigned. When necessary, the location of entrances (navigation points) to the POI is also noted. Any POI can have several entrances, which can be varied by type (entrance for vehicle, pedestrian entrance, …).
POI attributes data
The product is composed of a set of alpha-numeric tables. The "root" table stores just the POI center coordinates and id number. Additional tables stores information on classifications, attributes (such as name, address, and telephone no.), entrance coordinates (if exists), links to enclosed areas (universities, airports, etc.). Obligatory attribute data appears in two languages: Hebrew and English For example:
Among the categories coverd in the POI database are:
|Amusement parks||Government ministries|
|Authorities and institutions||Health|
|Banking services||Post offices|
|Culture and entertainment||Shopping and commerce|
|Educational institutions||Sports and leisure|
|Emergency services||Sports facilities|
|Events and festivities sites||Tourisam,travel and vacation|
|Fun and drinking spots||Welfare and community|
Several sub-themes can be listed for category. For example, following themes are listed under "Health" category:
Diet and nutrition
Medical clinics and laboratories
Rehabilitation and nursing institutions
Below the theme level comes the SIC classification describing the POI on the most basic and detailed level. For example, under "Hospitals" are 9 SIC classifications denoting the type of hospital. A particular POI can be attributed to several spheres just as it can also be described by several SIC codes. For example, a "Magen David" station can be attributed both to the "health" sphere as well as to the "emergency services" sphere.
