[Talk-us] Tampa/Clearwater Building Import to aid in Irma Recovery Efforts

Seems to be a lot of concerns for an import that is meant to bolster data
available prior to a major hurricane strike, when HOT does a task in Africa
I often don't see the same level of concern about the armchair mapper's
local knowledge.  That's just my observation, and I have worked some tasks
for HOT, and I have also done editing for places in the Middle East in
relation to a project I was doing for a customer and I have never come
close to stepping foot in any of those countries.  I know there are many in
the global community that have aversions to imports but if the process can
be held to a great standard, and in the face of a natural disaster, I think
we can put aside our own biases on how the map is made better.

As to the Texas statements, I have lived in Texas my whole life and have
worked for several local/state governments/parties.  There is a strong
backlash within some communities about sharing anything that cannot have
cost recuperated.  It is a stance that is slowly changing due to the strong
push from communities such as OSM, but it hasn't reached the level of other
states or countries.  Part of the problem is that there isn't a central
authority in charge of data.  You have council of governments that produce
data, counties that produce data, the state that produces data, state
agencies that produce data, and local governments that produce data.  Much
of the data could be said to be duplicated efforts but there hasn't been a
strong push from the legislature or the governor to have anything close to
a centralized data portal.  You can add to that problem the inability for
many counties and towns to afford GIS (something I'm hoping to help with as
part of my business) or GIS professionals to make data, let alone to
purchase data when it is offered.  The other issue is licensing.  I live in
North Texas and when the different communities up here get together to fly
aerials and derive planimetrics the operation is carried out by the North
Central Texas Council of Governments, which hires a company to do the
work.  When the work is done the cities that signed up for the project pay
the COG for the data and the COG pays the contractor.  In this process the
data is licensed so that only those who pay for it can use it.  That means
that many of the building footprint data sets are prevented from being
listed as open data because of the license involved.  With TNRIS releasing
LiDAR data openly hopefully some of this will change but for now it is what
it is.

That's my two cents worth on this, I think getting the data in is
important, especially as many of the government entities and news
organizations are using OSM data backed maps for base maps in the disaster
management process.  For example NOAA used a MapBox basemap for their post
Harvey aerial map (https://storms.ngs.noaa.gov/storms/harvey/index.html) I
think it would be important with the high visibility the map is getting in
the US to make sure that it accurately reflects reality on the ground.
