Historical Forest

Quantitative information about historical changes in natural ecosystems is important for guiding management interventions. However, few accurate data sources are available for documenting long-term vegetation changes. In this paper, we describe a neglected source of quantitative information on historical forest structure: forest inventory strip surveys, which were widely used in eastern Australia from 1915 to the 1940s. Strip surveys provide quantitative information on the species composition, stem density, basal area, stem form and size class distributions of dominant tree species. Such information is not available from other widespread data sources. Strip surveys usually surveyed 10% of the total forest area. In this paper, we describe the original survey methods, demonstrate how to decode data-book entries, and analyse a sample dataset from the Pilliga State Forests in northern New South Wales to illustrate the information that can be obtained from this material. Strip survey data-books are poorly archived. Many books exist for Eucalyptus–Callitris forests in northern and central NSW, and additional books may exist for many other forest types in eastern Australia. Strip surveys provide a valuable data source for studying long-term vegetation changes in forest ecosystems. We urge forest managers to search for and preserve this precious archival material.

Resource Data

Along with the rapid development of economy, strong demand has been put on the application of basic geographic information data which needs timely updating. It has become a subject to be further investigated to make full use of other data (such as forestry resource data, land survey data, etc.) to effectively add new data when the basic geographic information data is updated and ensure the timeliness of basic geographic information data. This paper gives an instance to describe and discuss a novel method, whose purpose is to quickly update basic geographic information data by forestry resource data on MicroStation V8 platform.

Indonesian Railroad Academy Madiun is one of the education UPTs under the Ministry of Transportation which houses the railway sector. To support education in the Madiun API and in accordance with the 2017 Revised Madiun API Master Plan, it is necessary to have additional lines, namely the Madiun API outer ring. Autocad Civil 3D software is very useful in providing an innovative, effective and efficient solution in the process of planning civil engineering specifically for the manufacture of railroad lines so that it is easier, faster and lower cost with the methodology of working on inputting land survey data and carrying out the next alignment design automatically cutting pieces of data transverse, longitudinal, gallian volume and auto fill have been obtained. The planning data that is the speed of the plan used is 30 km / h with a track width of 1,067m. design length of 1234,187m with a slope of 0,0009 or 0.09% below the maximum standard of 10 per ‰, cumulative fill 15584.68 m³ and comulative cut 5719.08 m³.
