[talk-ph] Mapbox Satellite imagery updates (May 2017)

[Jherome Miguel]

Finally, the long wait for more recent and detailed imagery for tracing in
OpenStreetMap, especially in Metro Manila and Calabarzon, has come.

Mapbox Satellite has released new imagery of Metro Manila, Bulacan,
Pampanga, Cavite,  Batangas, Laguna, and Quezon for tracing in
OpenStreetMap. The newly released imagery replaced cloudy imagery on
southern Metro Manila, Cavite, part of Laguna, Batangas and Rizal, and
imagery possibly taken between 2010, 2011, or 2012 (and also used by Bing)
in areas in Cavite and Laguna. Most areas of Batangas not previously
covered by Mapbox Satellite, like the rest of Lipa, Cuenca, Alitagtag, San
Jose, Batangas City, Ibaan, Lobo, and Taysan, have finally received more
recent imagery, possibly taken in early or mid-2016. This allowed more
detailed mapping and mapping the latest developments on areas in Batangas
where Bing has older coverage (e.g. western Batangas, eastern Lipa, Padre
Garcia, Rosario, and part of San Juan, which has imagery dated April 2010
or April 2013), cloudy imagery (e.g. parts of San Jose and Ibaan) or no
imagery (e.g. western Rosario, rest of Taysan and San Juan, and some
barangays of Batangas City, near the boundary with Taysan). I took some
time to map missing features (e.g. streets of the poblacion of Taysan, some
buildings and the San Jose Cockfighting Arena in barangays Calansayan and
Aguila, San Jose, a creek near barangay Lapu-Lapu in Ibaan, an NGCP 69 kV
line near barangay Malainin, Ibaan, and the Puyat Steel Plant in barangay
Masaya, Rosario) and recent developments (Camella Solamente and San Gabriel
Power Plant in Batangas City), using the latest imagery.

Aside from Batangas, Quezon (western areas), Bulacan, Pampanga, Bataan, and
parts of Tarlac and Nueva Ecija received new imagery. The latest imagery in
Quezon replaces the blurry imagery that once covered the areas from Tiaong
to Atimonan, including Lucena. The new imagery in Rizal included the area
from Tanay to the boundary with Laguna in Pililia, and the 54 MW Pililia
Wind Farm is shown in detail. Bulacan, which is also covered by the past
update has newer coverage, which also includes Pampanga, Bataan, Zambales
(Olongapo, including parts of Subic Bay Freeport Zone), Tarlac (up to
Tarlac City anc La Paz), and Nueva Ecija (up to Zaragoza, Jaen, and western
part of Santa Rosa)

Happy mapping.
