Please I am currently working on a project that requires knowing the number of houses in a semi urban area. There are no house census data available currently. I tried using google earth and painstaking counting the houses. This method is prone to errors. Please any suggestions?
Probably this website can be of an assistance to your work, it offers more layers to work with.

I am not sure where you are from. In the US, the county assessors have data on each parcel, including residential use and number of units. That would be the most direct way, although the number of units might not be completely accurate. Using air photos, it would take some air photo analysis skills. I would generally look for driveways, structures and fence lines or tree lines to identify rural residential uses.
Linda Tomaselli I am in Nigeria where such data are not available. Thank you so much for your suggestions. Regards
Cities in developing countries keep on growing in a rapid and uncontrolled way. In order to support public actions related to the monitoring of and interventions in the urban environment, targeted at providing its inhabitants with fair and balanced access to housing, social infrastructure, public transportation, sanitation, and other public services, it is essential to have updated information on the dynamics of both urban and demographic growth.
I am skeptical about census data, but as you also mention the word aerially I would recommend to deal with droning.... If you are interested I can provide more information...
Eberhard Weber Please I am interested in more information.
