This paper describes the GIS system developed for the Pemex’ pipeline network in the Valley of Mexico. The pipeline UTM coordinates, which are the basis of the GIS, were obtained from the high accuracy Geopig® inertial and caliper surveys. The survey data also included information on pipeline features and anomalies, and was incorporated into the GIS together with the metal loss data from the past in-line inspections. The system is based on the ArcView® GIS Software with the Arc View 3D Analyst™ extension that allows both the cartography and pipeline data to be viewed in 3-D space. It stores information on pipeline plan, profile, girth weld locations, dents, wall thickness, bending strains, metal loss and other features in relation to known landmarks such as roads, buildings, political boundaries and hydrology. This allows for very efficient and accurate location of pipe defects and anomalies, which is particularly beneficial where there are several pipelines running in the same right-of-way. It helps to eliminate unnecessary excavations, as well as to coordinate, plan and schedule pipeline repairs. The additional benefit of a multi-pipeline GIS system is the ability to store various information for all the pipelines in one database, which is easy to manage and update. The GIS also gives the ability to plot detailed maps, query data for effective solutions and visualize scenarios.

The last 25 years has been a period of rapid change in the approach to archaeological fieldwork in Britain and this has been reflected in the development of survey within the Royal Commission on the Ancient & Historical Monuments of Scotland (RCAHMS), the government financed body responsible for maintaining the national record of archaeology and architecture. The monolithic county-based inventory approach of RCAHMS' first 60 years has been replaced by a more broadly-based archaeological strategy founded on programmes of work that range from national overviews and regional surveys to individual site plans. Archaeological mapping has superseded monument planning as the key field objective, and all survey, whether terrestrial, aerial or desk-based, is underpinned by the RCAHMS Geographical Information System (GIs). The radical changes in field data-capture have been mirrored by parallel developments in making that data accessible once it has been collected.

Model nilai tanah merupakan model untuk menaksir nilai tanah berdasarkan faktor-faktor yang dikenal pasti dapat mempengaruhi nilai tanah. Secara umum ada empat (4) kumpulan faktor yang mempengaruhi nilai tanah iaitu struktur, kejiranan, lokasi dan masa. Sebahagian besar daripada faktor ini memerlukan data ruangan yang dahulunya sukar dijana kerana kekurangan alatan yang sesuai. Perkembangan dalam sistem maklumat geografi (GIS) membolehkan berbagai-bagai jenis analisis ruangan yang diperlukan seperti pengkelasan semula, penindanan, pengukuran jarak dan kehampiran, kejiranan, rangkaian dan permukaan dapat dilakukan dengan lebih mudah. Kajian ini cuba membentuk satu model nilai tanah dengan memfokuskan kepada faktor struktur. Sebanyak empat pemboleh ubah struktur lot tanah diambil kira iaitu keluasan, lebar hadapan, indeks landskap (bentuk lot) dan arah orientasi. Kaedah statistik yang digunakan adalah analisis regresi terhadap sampel 148 transaksi lot tanah. Daripada analisis hanya dua pemboleh ubah iaitu luas dan bentuk lot signifikan pada tahap 0.05 dan berjaya menerangkan sebanyak 74% daripada variasi nilai tanah. Kata kunci: nilai tanah; GIS; faktor struktur A model of land value is a model to estimate land value based on factors identified to influence land value. Generally, there are four groups of factors that influence land value i.e. structural, neighborhood, location and time. Most of these factors need spatial data that were difficult to generate in the past due to the lack of appropriate tools. The recent development in Geographical Information System (GIS) enables the various spatial analysis such as reclassification, overlay, distance measurement and proximity, neighborhood, network and surface analysis to be a carried out with ease. This study attempts to develop a land value model with a particular focus on structural factors. Four structural factors were considered in the model namely size, width of frontage, landscape index (shape of lot) and orientation. The model was developed using multiple regression analysis based on a sample of 148 lots of land transaction. From the analysis, only two variables i.e. size and landscape index were statistically significant at 0.05 level and successfully explained 74% of the variation in land value. Key words: land value; GIS; structural factor

Kertas kerja ini membincangkan kajian literatur mengenai proses awal yang perlu dititikberatkan dalam pembangunan suatu GIS (Geographical Information System). Dalam pembangunan sistem maklumat geografi (GIS), proses penukaran data (data conversion) merupakan proses awal yang perlu dilalui untuk mencapai kepada tahap pangkalan data geografi yang bermutu tinggi. Proses ini juga biasanya merupakan sebahagian terbesar daripada keseluruhan projek GIS dan secara tidak langsung kos untuk proses tersebut juga adalah yang paling tinggi iaitu dalam lingkungan 60%. Dari segi terminologi pula, terdapat dua aspek proses penukaran dan di dalam kertas kerja ini salah satu aspek yang akan dibincangkan iaitu dari segi persediaan awal berkaitan dengan spesifikasi projek penukaran, spesifikasi data dan spesifikasi pentadbiran harus dilaksanakan sebelum proses penukaran (conversion) dapat dijalankan dengan lancar. Setiap sistem AM/FM pula, memerlukan kepada satu dasar tanah yang tepat, terkini dan selaras dengan tempat data fasiliti dirujuk secara geografik. Dengan lain perkataan, tanpa dasar tanah, sesuatu sistem pemetaan tidak boleh dikatakan sebagai satu GIS. Beberapa teknik perolehan dasar tanah dibincangkan dengan serba ringkas untuk membolehkan perhatian ditumpukan kepada masalah penyediaan dan pembersihan data fasiliti yang akan dirujuk terhadap dasar tanah ini kelak. Pembersihan data fasiliti adalah amat perlu supaya data yang dimasukkan semasa proses penukaran berada dalam keadaan baik dan tidak mendatangkan masalah semasa penggunaan kelak. Ini juga dapat menjimatkan kos pengguna dalam jangka masa panjang. Mutu maklumat yang akan ditukar juga perlu diambilkira.

In the development of a GIS, data conversion is the initial process that one has to undergoe in order to achieve a geographic of high quality. This process often constitutes to more than half of the total of a GIS project and indirectly the cost for this process is usually around 60%. In terms of terminology there are two aspects of data conversion in a GIS namely, conversion of analogue/manual geographic data to digital form which involves manual sources such as paper maps, drawings, digital form etc. and conversion from one GIS system to another GIS system of different format. In this paper only the first aspect will be discussed in depth regarding early preparations to be considered in the data conversion and this pertains to project specifications, data specification and administrative specifications. Every GIS requires a current, uniformly accurate landbase to which the facilities data can be geographically referenced. In other words, a computerised mapping system is nota a true GIS if it is not referenced to land base. Techniques on land base acquisition is disscussed in brief to allow the author to express in detail problems concerning the importance of data preparation and purification before the final conversion takes place. Data preparation and purification is viable so as not to input 'garbage' and 'output' garbage as well. Quality control on data to be converted should also be taken into consideration.

Abstract Hour-al-Azim marsh is one of the most significant wetlands of the Mesopotamia watershed. In the past few years, severe environmental and hydrological stress have caused the loss of a large part of its area and its bed has become the largest focal point of haze in the southwestern of Iran. Determining delineation is one of the most important and necessary measures to protect a wetland's ecosystem and, in this study, delineation was determined using the USACE-R-G method. This method is a combination of ecological and hydrological criteria with a Remote Sensing and Geographical Information System. The results showed that under the first scenario the marsh is about 3,279 km2 which about 882 square kilometers constitute free-water surface and its average depth is 2.4 meters. In the second scenario, these numbers were estimated to be 1,619 km2 with an average depth of 2.7 meters. Moreover, the area of the haze focus is about 1,659 km2. As well as this, under these conditions the amount of water required to submerge the marsh is 7.9 in the first scenario and 4.4 billion cubic meters in the second one.

Since 2004, the Cicrp: &ldquo;Centre Interr&eacute;gional de Conservation et Restauration du Patrimoine&rdquo;, located in Marseilles has been involved in an interdisciplinary research program dealing with infestation and re-infestation, on lining pastes used in painting conservation, by the <em>Stegobium paniceum</em> through a GIS system : a geographical information system called &ldquo;StegoGIS&rdquo;. The GIS helps understand the insects ethology in its environmental context, mainly in flour and semolina millings in order to determine analysis criteria to prevent, mitigate and fight infestation in the cultural property environment. Our approach is based on three main lines: 1- A transverse approach of infestation in any type of cultural heritage institution: archives, libraries, museums, historic buildings where organic material collections and environment are attractive on an &ldquo;insect point of view&rdquo;. 2 &ndash;An IPM strategy (Integrated Pest Management) including conservation and management of collections and buildings also based on an infestation survey with actual or potential risks. 3- A &ldquo;decision- making tool&rdquo; in diagnosis, preventing methods and treatments for professional conservation staff.

Groundwater is imperative for the continuance of life and sustainability of ecosystem. Contamination of the water is the well-recognized danger to the public health in Pakistan. Hence, this study was conducted to assess and map the spatial variation of groundwater quality in the surroundings of Dijkot Branch Drain by using the Geographical Information System(GIS). For this purpose, sixty samples of groundwater, ten samples of wastewater and five samples of sludge were collected along with their coordinates from the study area. The collected samples were analyzed for chemical parameters and heavy metals, such as pH, EC, TDS, Carbonates, Bicarbonates, Arsenic, Lead, Chromium, Cadmium, Zinc. The results obtained from the study were compared with WHO guidelines. Then, the values of these water quality parameters were mapped by using GIS software. Arc GIS V 10.2 was used for raster interpolation. To exhibit the spatial variation of groundwater quality scenario of the study area, Kriging method was adopted. on. It was generally observed that none of the parameters in the wastewater samples was found to be within the permissible limit. The research study resulted that the groundwater of the study area is deteriorated by Dijkot Branch Drain and is not fit for drinking purpose.

The characteristics of the landcover of a territory were really influenced by the condition biophysical and social his community’s economics. To the territory with the high rainfall had a rare population, the pattern of the landcover was more dominant to the annual crop, conversely to the high rainfall territory had a solid population the pattern of the land cover was more dominant in crops. Whereas to the dry territory (low rain) with the rare inhabitants, the pattern of his land cover was dominated the meadow and the crop kept dry. The requirement would the latest data, the high accuracy, to the area that was wide to monitor the change in one unity of the management of watershed. This research aimed at studying the application of remote sensing (RS) and the geographical information system (GIS) to monitoring and the evaluation of watershed. Physical conditions for the land that was dominated by the land form of the mountainous land and hills with the slope that was steep until precipitous, caused the territory around Grindulu Sub Watershed the potential would the occurrence of the landslide. This landslide incident was also supported by the rock situation that has begun to go mouldy resulting from the disintegration by the hot influence and rain as well as decomposition. Although having some areas of the land that was dominated the bare-rock and the rock-outcrop, but because the land cover was relatively dense in the area of mountains and hills then year round the Grindulu river had not been dry.
