Hello I am making a map for an app and I have a problem were the static image will change when the zoom is changed but the longitude and latitude don't so I end up with data points in the same place at every zoom
I am looking for a solution that allows me to change zoom and the longitude and latitude will change so that I can actually see the data points at every level
Here is my expressions:
Longitude - =SUM( round (256*pow(2,($(var_zoom)-1)))+( longitude *((256*pow(2,$(var_zoom)))/360)) )
Latitude - =SUM(((256*pow(2,($(var_zoom)-1)))+((0.5*log((1+(sin((latitude)*pi()/180)))/(1-(sin((latitude)*pi()/180)))))*((-256*pow(2,$(var_zoom)))/(2*pi())))))
And this in my script:
// Google Maps Key
gmap_key = 'AIzaSyAASA7qdksCLnQJcvMlgrFvPi10puehhKc';
max_zoom_level = 14;
def_zoom_level = 7;
def_map_size = 401;
// Variables required for calculating map
var_pi180 = '=pi()/180';
var_lat_offset = '0';
var_mc2 = '=256*pow(2,$(var_zoom))';
var_mc1 = '=256*pow(2,($(var_zoom)-1))';
var_mid_lat = '=median(latitude)';
var_mid_long = '=median(longitude)';
var_zoom = '=if(max(aggr(if(max(round(256*pow(2,(_zoom_level-1)))+(Longitude*((256*pow(2,_zoom_level))/360)))-min(round(256*pow(2,(_zoom_level-1)))+(Longitude*((256*pow(2,_zoom_level))/360)))<def_map_size AND max((256*pow(2,(_zoom_level-1)))+((0.5*log((1+(sin((latitude)*pi()/180)))/(1-(sin((latitude)*pi()/180)))))*((-256*pow(2,_zoom_level))/(2*pi()))))-min((256*pow(2,(_zoom_level-1)))+((0.5*log((1+(sin((latitude)*pi()/180)))/(1-(sin((latitude)*pi()/180)))))*((-256*pow(2,_zoom_level))/(2*pi()))))<def_map_size,_zoom_level,null()),_zoom_level))>def_zoom_level,max(aggr(if(max(round(256*pow(2,(_zoom_level-1)))+(longitude*((256*pow(2,_zoom_level))/360)))-min(round(256*pow(2,(_zoom_level-1)))+(longitude*((256*pow(2,_zoom_level))/360)))<def_map_size AND max((256*pow(2,(_zoom_level-1)))+((0.5*log((1+(sin((latitude)*pi()/180)))/(1-(sin((latitude)*pi()/180)))))*((-256*pow(2,_zoom_level))/(2*pi()))))-min((256*pow(2,(_zoom_level-1)))+((0.5*log((1+(sin((latitude)*pi()/180)))/(1-(sin((latitude)*pi()/180)))))*((-256*pow(2,_zoom_level))/(2*pi()))))<def_map_size,_zoom_level,null()),_zoom_level)),def_zoom_level)';
var_maptype = '=if(isnull(only(maptype)),fieldvalue('&chr(39)&'maptype'&chr(39)&',4),maptype)';
// Calculate best zoom level
set HidePrefix = '_';
_zoom_level:
LOAD RecNo() as _zoom_level AutoGenerate(max_zoom_level);
maptype:
LOAD * INLINE [

I really need the help and would appreciate anything
