Good Day!

I would like to respectfully request on any available coordinate position (geographic and PPCS/PTM both in PRS92 and Luzon 1911, both within Zone V) of the following monument stations:

1. Triangulation Station Uso Gigoso aka SME 5, a 1st Order Triangulation Station established in 1907 at the Brgy. Gigoso, Municipality of Balangiga, Province of Eastern Samar.
2. SME 3, a 1st order triangulation station established in 1990 at Brgy. Bato, Borongan, Eastern Samar
3. SMR 5, a 2nd order triangulation station established in 1990 at Zone 3, Catarman, Nothern Samar
4. BLLM No. 1, Cad 434-D, Borongan Cadastre
5. BLLM No. 1, Cad 430, Guiuan Cadastre

I am checking/verifying my current data on hand against the official data from your good office as part of my due diligence research before conducting subdivision surveys (contractual work under DAR) on CCLOA lots nearby.

I hope for an immediate response on this humble request at the soonest time possible (preferably within 3-day time frame).

Thank you so much in advance. God Bless!

Sincerely,
R.L Caliwan, RGE
