Making Air Pollution Maps from Scratch

[@moo_moon128]

Amaing ma'am, you taught me more than the teacher in my training course.

[@chemtrailsmoker]

Thanks for this upload its a lifesaver 🙏🏿

[@GalibW]

Thank you Dr Mollalo for very informative presentation

[@HealthGIS]

You are very welcome

[@031dhanu]

This is what I was looking for. Thank you very much. Very informative video.

[@MrDanty64]

Putting aside my criticisms of the default in the mask of the area that you wanted to create the model of (OH, I forgot, it might help to define what the 3 letter acronym is in the Spatial Analyst extension tool box that you used?), like Rei Jirou said, this IS HUGE!

[@fredwooten14]

Great video series!!❤💯

[@DB-kv3wu]

Best!

[@mwikwabejoseph367]

how can i get air quality data for the whole world?

[@Mike_more]

Please how can I diwnload PM 2.5 data in Nigeria

[@simateimourianmotlagh2023]

I would be thankful if you share shapefiles which are necessary for this project , I could not find them on the net.

[@HealthGIS]

You can freely download the administrative boundaries shapefile from TIGER/Line.

[@nareshbhukya8359]

U didn't explained about counties_OH ? Where should I get ?

[@HealthGIS]

You can download the shapefile for the entire United States from TIGER/Line US Census Bureau: www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.html

[@JohnSmith-nl5ez]

Hi there, I have a problem that my dots do not match up with my map. I have tried to get the location of weather stations for Chicago, do you have any help?

[@HealthGIS]

This is because you are not using a proper map projection. If you use UTM make sure to set the coordinate system for zone 16N.

[@annisaariyanti5443]

The data that available only for US

[@joshhermosillo37]

How can you do this showing counties?

[@HealthGIS]

You need to have counties boundaries (I downloaded it from TIGER/Line) and knowledge of using ArcGIS. Please refer to other vids in the channel, fully explained.

[@joshhermosillo37]

HealthGIS Lab thank you

[@fredwooten14]

Her video finding data video you can check the box for counties.

[@johnlemes]

thanks for your video. How you can stretch the interpolation raster to cover all the Countries_OH.shp you have? These gaps are not very nice!!

[@HealthGIS]

Please note you cannot extrapolate outside of data points ( climate stations), to address this issue, you need to have climate stations of neighboring states as well.

[@MrDanty64]

@@HealthGIS Shouldn't have to worry about neighboring states--should be able to create a DEM or something similar that covers just Ohio and not anything else. Why not merge the counties layer for starters and remove boundary lines? I will have a heart and at least recognize that this was all done in ARC MAP (!) so I will take a knee too but at the same time something still feels off to not be able to extrapolate from all points within a certain polygon file....
