Dear Bapak Plmpinan Pemerintahan/ lnstansi Terkait

Thank you for your interest In our products and services,

We are pleased to provide you wilh the followIng quote for lOem pixel resolution Drone

Aerial Photography. Oelailed City Mapping, Tata Ruang and Countur in Kabupaten

/ Province , in Indonesia.

For the past:; years we have speclatized In high resolution salelfile Imagery. Recent and usable satelHteimagery Is ollen nolavailable and new satellite Imagery can take several months 10 acquire. For new plantings, even the best avaiiabJe50cm pixel resolution satellite Imagery is lnaeequete. This is why we Ilave been explOffngother solutions to deliver faster and map completely. Our new Drone aerial photography provides an excellent solution,

Each block WIll be measured accurately: land ooverfland use, conservation areas, roads, drains, rivers, bridges and aD other surface features will be mapped, Each visible Countur; Vacant areas will be oullined and color-shaded maps will be produced.

Our new Drone aerial photography provldes an excellent sofutioo for your Inquiry. Some of the advantages of the Drone (Unmanned Aerial Vehide) for Clly mapping are:

Regrds,

Drone Aerial Photography	High Resolution Satellite Imagery

· 10cm x 10cm pixel size (25 times	· 50cm x 50cm pixel size
sharper than the best satellite
imagery available)
· 0% cloud cover (fly under the clouds)	· Up to 15% cloud cover
· Collected in less than 1 month	· Collected in 5 months on average (due
	to heavy cloud cover in the region)

· Can count nearly all palms	· Difficult to count all palms, especially <2
(except in areas overgrown with	years old
cover crop - mucuna or very small
newly planted palms.

Drone Aerial Photography some advantages over traditional aerial photography taken from fixed-wing planes:

No security clearance / permission required.
No security officer required to accompany plane or survey.
Flexible short flights. Even with two or three hours of clear weather the Drone will fly.
The fixed-wing plane would not.
No additional charge for standby days.
No risk to human lives or property.

Since late 2010 we have successfully made 300 drone flights equaling 100,000 individual frames combined to create 30,000 hectares of seamless ortho-mosaics.

The flight teams, Remote Sensing teams and Surveyors will be provided by EarthLine. Approximately 30 High accuracy (sub-meter accuracy horizontal and vertical) Ground Control Points will be collected throughout the estates that will be used to create the air photo ortho-mosaic (geo-referenced) and to produce Digital Terrain Model.

In order to achieve this high accuracy, we will establish a permanent local benchmark within the estate using Bakosurtanal’s GPS reference point network. Instead of a lower accuracy Differential GPS Survey using Trimble GeoXT/GeoXH Rovers, Ground Control Points will be measured with by a Rapid Static GPS Survey using Trimble Dual- Frequency Geodetic GPS Receivers.

The air photo frames collected in the field will be processed using the Ground Control Points with our advanced air photo processing software resulting in air photo ortho- mosaics and Digital Terrain Models. 2.5m contours and six-class slope maps will be derived from the DTM.
