PEDRO Center – Philippine Earth Data Resource Observation
By Princess Angela D. Young
Philippine Earth Data Resource Observation Center (PEDRO) established a Satellite Ground Receiving Station (GRS) facility with direct access to a broad range of optical (high-resolution,multispectral) and radar (cloud penetrating, day-night-imaging) satellite data.

The Philippine Earth Data Resource Observation (PEDRO) Center installed the first satellite tracking antenna in the country and established a Ground Receiving Station to access earth-surface information for disaster management, environmental monitoring, national security, urban mapping, rehabilitation assessment, and research purposes.
Since its inception on December 2016, PEDRO Center has stored, archived, and delivered 1300+ images to various agencies. During the first quarter of 2018 alone, a total of 326 images were distributed. These images were used to cover relevant areas and events like Typhoon Agaton, Mayon Volcano Emissions, Marawi Siege and Rehabilitation, Mt. Pulag Forest Fire, and Kalayaan Group of Islands. The project serves as a platform for different agencies to access relevant earth surface data.
All these efforts are targeted to make scientific and technological advancements in space exploration and in gathering earth surface information.
The Department of Science and Technology - Advanced Science and Technology Institute started developing its Information and Communications Technology for the Space Program as a co-implementing agency of the PHL Microsatellite Program in 2014. On April 26, 2016, the program successfully launched the Philippines' first Microsatellite, DIWATA-1.
With this, DOST-ASTI implemented the PEDRO Center Project to establish a Ground Receiving Station that will complement the operations of DIWATA-1. The project installed the first satellite tracking antenna in the Philippines. This allowed the ground receiving facility to directly receive image data and to upload commands like captures and download of images from DIWATA-1.
The PEDRO Center expanded its connection to various satellites for better earth surface data collection. Currently, PEDRO can directly download images from DIWATA-1, KompSat- 3, and KompSat-5. The GRS can also access data from KompSat-3A, KompSat-2, GeoEye-1, WorldView-1, WorldView-3, Worldview-4, Cosmo-Skymed, PlanetScope, RapidEye, and SkySat. Through these satellites, the PEDRO Center gather wide-range of data for different purposes.
Moving forward, PEDRO aims to continuously provide accessible earth surface data and expand its connection to different satellites. By the end of 2018, PEDRO aims to establish a second Ground Receiving Station in Davao City in partnership with the Civil Aviation Authority of the Philippines, Department of Information Communication Technology, and Department of Science and Technology Region XI. The Davao Ground Receiving Station will have a larger moving antenna with 7.3m diameter and will be capable of receiving higher frequency of data.

Images from PEDRO Center supported the following agencies
Philippine Institute of Volcanology and Seismology
The Philippine Institute of Volcanology and Seismology (Philvolcs) as a service institute of the Department of Science and Technology is mandated to mitigate disasters caused by volcanic eruptions, earthquakes, tsunami, and other geotectonic phenomena.
The PEDRO Center supports Philvolcs in mitigating disasters through providing images. During the volcanic emissions of Mount Mayon last January 2018, the PEDRO Center provided images to PhilVolcs to aid in determining the danger zones and for pre and post disaster assessment. The PEDRO Center also aided PhilVolcs during the Typhoon Vinta, Typhoon Urduja, and Leyte Earthquake.
National Mapping and Resource Information Authority
The National Mapping and Resource Information Authority (NAMRIA) provides the public with mapmaking services and is the central mapping agency, depository, and distribution facility for natural resources data in the forms of maps, charts, texts, and statistics.
The PEDRO Center provides images to NAMRIA for land use and land cover classification (particularly in Antique, Davao, Occidental Mindoro, Negros Oriental, Sarangani, and Sorsogon) and coastline mapping (Boac, Marinduque).

How to Request Images
The PEDRO Center provides images to government agencies or government attached institutions only. To acquire images from the PEDRO Center, kindly email the following details firstname.lastname@example.org
- AOI (Areas of Interest) (place names, shapefiles [shp], google Earth [kmz/kml] files)
- Satellite data type (Optical or Synthetic Aperture Radar [SAR])
- For Optical data, band requirements (Ex. RGB, NIR, SWIR)
- For SAR data, polarization requirements (Ex. HH, VV)
- Spatial resolution or Ground Sample Distance (GSD)
- Image acquisition dates (Ex. 2016 to 2017 archives, latest available, new tasking at a specified date)
