Anylogic GIS programmatically search for schools in a given location

Question

Without using the search option in the GIS map in anylogic, I want Anylogic to take a user input which is the name of a location and then place an agent in that location. Then, as the model runs I want it to search for schools near that agent/location found earlier. Then I want the schools found to be made into a collection. This is then important for me to compute some aspects further. How do I do this using functions/codes in Java.

I am able to achieve all this using individual search in the search window of GIS map in anylogic. But I want it to happen such that once a user types a location as a user input in the simulation window( using a parameter or so), automatically the map places the agent there and then searches schools and then places agents there and then these agents become a collection which will be used in another function for computing. I want to automate it using codes.Please help. Thanks in advance.

You will need to set up a population of your agents and specify their initial location based on a parameter that you create inside your custom agent.

For this simple example, I created variable location of type String where a user can input the location where you want to search for a school.

Then inside the create Agents button I added this code

// Find the location we are searching for as a GPS point
GISPoint point = map.searchFirst(location);

// Set the visible map to this location
map.setCenterLatitude(point.getLatitude());
map.setCenterLongitude(point.getLongitude());
map.setMapScale(1/1000000.0);

//Set the search parameters to be within a range from the location we got
map.setSearchBounds(point.getLatitude()-5, point.getLongitude()-5, point.getLatitude()+5, point.getLongitude()+5);

// Search for points within the map serachable area and for each create a new agent.
List<GISPoint> schools = map.search("School");
for (GISPoint gisPoint:schools){
    add_myAgent(gisPoint);
}

It works when testing, however, the results for Schools in the searchable area around New York were very small. But this is the case even when doing it manually.
