Hi, I noticed the following API request:

https://api.dhsprogram.com/rest/dhs/surveys?surveyCharacteri sticIds=26&surveyStatus=completed&surveytype=DHS& ;f=html

Excludes some surveys that have GPS datasets (surveyCharacteristicIds=26), for example, Cambodia 2021, Jordan 2017, Mali 2018, Nigeria 2018, Philippines 2017 and Tajikistan 2017 all have GPS datasets, but do not show up in this API call because code 26 is not in their "surveyCharacteristicIds" column.

they do show as available in the datasets query, although not clear how to filter the API call. https://api.dhsprogram.com/rest/dhs/datasets?DatasetType=GPS Datasets&f=html

Thank you for flagging this issue. There were 17 surveys with a missing survey characteristic 'GPS/georeferenced'. They have all been updated in our database and are listed below. To filter the API call for georeferenced datasets, use this link https://api.dhsprogram.com/rest/dhs/datasets/?fileType=GE&am p;f=html

Thanks Blake,

The call by surveyCharacteristicIds=26 still does not bring up the same list as the one by fileType=GE.

https://api.dhsprogram.com/rest/dhs/surveys?fileType=GE& surveyStatus=completed&surveytype=DHS&f=html (328 records)

https://api.dhsprogram.com/rest/dhs/surveys?surveyCharacteri sticIds=26&surveyStatus=completed&surveytype=DHS& ;f=html (198 records)

If I remove the survey status query, the numbers are still different, and smaller (not what I would expect with a less restrictive query).

https://api.dhsprogram.com/rest/dhs/surveys?fileType=GE& surveytype=DHS&f=html (313 records)

https://api.dhsprogram.com/rest/dhs/surveys?surveyCharacteri sticIds=26&surveytype=DHS&f=html (193 records)

You cannot specify a fileType in a surveys call, only in a datasets call. Below is the correct call for each.

https://api.dhsprogram.com/rest/dhs/surveys?surveyCharacteri sticIds=26&surveyStatus=completed&f=html
https://api.dhsprogram.com/rest/dhs/datasets/?fileType=GE&am p;surveyStatus=completed&f=html

The number of surveys with GPS data collected will not match the number of geospatial datasets available because not all GPS data collected is publicly released for various reasons.

https://dhsprogram.com/data/available-datasets.cfm

If the surveyStatus is not specified, the default is surveys with data available in the API. Not all completed surveys have data in the API which is why the total would be less. Pending surveys also do not have data in the API until they are marked as completed.
