Where I can find canada postal codes geographic data? KML or something similar.
I can find US KML format geographic data here :
https://www.census.gov/geo/maps-data/data/kml/kml_zcta.html

I want to build a shape map in Power BI using postal area for Australia. I downloaded the Correspondence, 2011 Postal Area to 2016 Postal Area and converted it to json file type on mapshaper.
My data has a postcode column that looks like this:
and the map keys looks to be of the same format:
However, when I tried to plot the shape map by sales column (the value column), output looks like this
which doesn't zoom in. Is it because the data is too large? But there are only 300 rows in the table. How can I map out the areas by postcode?
No wonder your map loads slowly. You should simplify the map using Mapshaper. Start with that. There could be another cause of the slowness in your measure you put on the map color saturation. Start with the simplest possible measure such as SUM( Table[no of kangaroos] ), avoid SUMX or IF in that measure. You could use Daxstudio to check the performance of the measure.
In an excel sheet I have several countries listed for different job ID (ex: USA, Canada, UK, UAE, etc). However, once I load the data into power BI and select the map visualization, only one country is listed on the map. How do I get all countries from the spreadsheet be labelled on the map?
Maps are a big problem in Power BI.
You should add latitude and longitude columns for every country into your country table.
There are some map specific issue in Power BI which basically belongs to the Map Provider, not a Power BI Issue. For example, in ArcGIS map you have to provide value "United States of America" instead of "USA". Other wise the map will not going to detect that country appropriately.
For your example cases you mentioned USA, Canada, UK, UAE. Here in most case I guess it is related to the country name. Please try with providing full name of countries. You can aslo search Map wise supported country name from their documentation.
I am trying to compare data from census tracts over time, but some census tracts change from census to census. Is there a way to match up old census tract IDs with what the new census tract ID is? Specifically for 1990 and 2010 censuses.
I realize your question is several months old, but in case you still are wondering about this, (or for anyone who stumbles on here later) - the IPUMS project has geographic crosswalk files available on their website for 1990 blocks to 2010 blocks.
Those are available here:

Keep in mind that if you are doing spatial analysis the Census Bureau did some clean up of their geography, improving the accuracy of the boundary lines around 2008 and after so you may find some discrepancies if you're doing spatial overlays. See here for more info:

I'm doing airlines analytics in Tableau. I only have airport names but not country names. Airport codes can be turned into geographic airport, so they're automatically drafted on a map. Then I want to filter out only US flights. Can I generate a country dimension based on the map so that I can select US?
I have list of records with city name and it latitude and longitude.now i want to find a list of cities based on entered city and direction (north,south,east,west).e.g, if i enter city Mumbai and select dircetion east then it will display list of east side cities from Mumbai.so how to achieve this task.please if you have any solution then share it with me.
Thanks in advance.
A geographic location is expressed as its latitude (the distance north of the equator) and the longitude (the distance east of the Greenwich prime meridian).
Hence the scenario you describe is merely a matter of selecting the coordinates for Mumbai from your database, and then performing a separate query to return all cities with a higher longitude than the discovered value.
the logic is very simple, when the "select" tag containing the cities is "change"d, you need to send an ajax call to your .php file that retrieves the database values and ask it to find the selected city in the other table that contains the direction and list of the cities and then send them back to your .js file and place them in the desired select. with no code to show for, this is the only help I could give you!
