Author Topic: Proximity Search - Map Contacts - Default Zoom Level (Read 1845 times)

We use CiviCRM for our local residents association. We find the proximity search really useful for finding contacts within a small radius (100-150 meters). As it is small geographic area in which we operate with a lot of contacts (over 1800) searches can throw up a lot of contacts in a small area. When we Map Contacts on the search the resulting map is not clear as all the contacts are bunched together due to the default zoom level and we can't zoom in as we are maximum zoom, but we can zoom out. Is there a parameter where we can change the default zoom value when the map is first displayed?

On a Contact record display when we click on the map icon in the contact record, the zoom level is down at the lowest level and we could do with changing that to zoom out a little bit as default.

You can edit the zoom level in the relevant tpl files - just view source to find which tpl is called for any given page, then be sure to edit a parallel copy saved within your custom templates directory.

Hope that helps,

Hi davidunwinubs13,
rjb is right you need to edit /templates/CRM/Contact/Form/Task/Map/Google.tpl file .
Following line which is use to set defaultzoom value (around line -33 )

Code: [Select]

{assign var=defaultZoom value=12}

I tried changing the zoom which was set to 12 to other settings ie 10 and 14 and it did not make any differences. Are there other tpl files I should be changing? I have just changed the google.tpl file as we use google for the mapping.

Farther down in the file look for map.setZoom. There are two places where it doesn't use the default zoom and instead I think it's trying to calculate the appropriate zoom level but I've noticed that it doesn't seem to work. Replace those with map.setZoom({$defaultZoom})

Hi guys,
Thanks for that. I have not changed the other parts of the code as suggested yet, but I found the following:
When the Google map displays you have three selection boxes in the top right hand side of the map,
Map, Satellite, and Terrain.
By default Map Contacts displays the Terrain version of the map.

If you click on the Map selection to show the street names, The zoom level changes to what you specify in the Google.tpl file.
So this seems a good workaround.

Thanks guys for all your help on this

I made two changes:

Line 33: value=18 <== or whatever you're looking for to provide depth of zoom

Line 41: map.setMapTypeId(google.mapsTypeId.ROADMAP) <== changed from TERRAIN based on David's hint

I found the map types here:
https://developers.google.com/maps/documentation/javascript/maptypes

This works great for me.
