SYDNEY CBD LIGHT RAIL
A Survey Data Model (SDM) of the Sydney CBD and South East Light Rail Project (CSELR) was prepared for the planning and design process in conjunction with project surveyors Cardno Hard & Forrester. The SDM provides an accurate cadastre of the properties abutting the route of the project in a digital format that provides a dynamic, accurate and intelligent cadastral foundation within the project-specified ESRI Parcel Fabric GeoDatabase environment.

Mount Diablo Summit-Building Roof Promenade & Beacon Tower, Constructed by Civilian Conservation Corps, 1939-42
On a clear day one can see more land from the top of Mount Diablo than from anywhere else in all of the Western States. Because of its prominent position, Mount Diablo is the starting point for the establishment of land boundaries throughout most of California and all of Nevada. The summit is the location of the "Initial Point," the north/south meridian, and east/west baseline intersection point that is the basis for most property boundaries.
In July 1851, Col. Leander Ransom, General Land Office Deputy Surveyor, labored to the top of Mt Diablo in oppressive summer heat. Under instructions from the Surveyor General for California, he was to establish an initial point at the summit, through which the new Mt Diablo base and meridian lines would run. He chiseled a hole in solid rock on the highest point and erected a flagpole to be used as a sight to establish monuments on the base and meridian lines. Ransom then went due south twelve miles and set additional monuments to establish the meridian line. He continued setting monuments due east, due north, and due west of the initial point on the summit of the mountain, thereby establishing the Mount Diablo Base and Meridian lines.
One year later, in 1852, R. D. Cutts of the United States Coast and Geodetic Survey traveled to the top of Mount Diablo on a mission to establish a survey marker for mapping surrounding waterways and topography. The point established by Cutts is now marked by a copper pin at the base of the concrete pillar, in the basement of the summit tower and also a rectangular-shaped depression in exposed bedrock three feet northwest of the copper bolt marks Ransom's initial point. In July of 1993, land surveyors from around California gathered on top of Mt. Diablo to celebrate the installation of a new plaque commemorating the survey makers on the summit of Mount Diablo. The new plaque was placed on a concrete pillar inside the basement of the summit tower.
