有效管理灌溉网络

水成为一种稀缺资源,是growing importance to efficiently use it in agriculture, particularly in arid climates, where recent droughts have brought an urgency to develop techniques for monitoring water irrigation and crop productivity. Increasing irrigation potential in the command areas requires considerable efforts, both in terms of time and money. Advances in remote sensing and GIS have offered water resource researchers and managers a new and fresh way for obtaining accurate spatial data on actual water use, water demand, allocation and distribution of water, and crop yield. For these tasks, the Leica Geosystems Zeno 10 GNSS /GIS handheld device with Zeno Office software provides the ideal solution. It is easy-to-use for non-GIS professionals, customisable and upgradable, allowing enhanced performance and increased profitability in the field of asset collection & management. By simplifying data integration from field to office, rich geospatial data of assets is easily captured and managed with one simple workflow.

El协和建筑是一种社会组织lising in the design, engineering, management and construction of projects. The company has been contracted to define an integrated meticulous strategic plan for developing and managing water resources throughout Iraq in order to ensure sustainable management and development of the country’s water and land resources. Long-term project phases are seen for the future in 2015, 2020, 2025, and 2035.

This project, which has been developed for several areas, in particular for the locations along the Tigris and Euphrates Rivers and their main water courses, for a total area of 12,000 square kilometres (4,630 square miles).

Project planning and requirements
灌溉系统及其位置的所有调查功能都需要将其纳入改进的数据库中，以促进其计划。每个资产都需要通过功能进行调查。由于数据的性质和所需的准确性以及访问某些位置的困难，因此决定进行物理调查将比基于车辆的调查更具成本效益。

Collecting data with Leica Zeno 10
For such a large survey area, with high volumes of data and with work taking place regardless of weather the right choice of the right survey equipment was essential. El Concorde selected the Leica Zeno 10 GNSS/GIS handheld using Leica Zeno Field software due to its compatibility with the existing Esri based GIS, its excellent mobility and its screen performance. In addition, the Leica Zeno GIS solution offers reliable technical support and this is essential when adopting new equipment into a business or project. A key element of ensuring rich asset detail was captured at the point of survey, making sure all data could be captured in a single visit. The integrated camera on the Zeno 10, which helped to document features with images, was invaluable for internal quality processes and assessments, and enabled the staff in the office to easily understand documentation, making it easier for them to work together and ensure the right data was captured at the time. This way, revisits were eliminated, thus minimising costs and delivering datasets without delay.

A simple workflow chain
The Leica Zeno GIS solution ensures efficient workflows by reducing trips from the field to the office because it offers the ability to monitor data captured in the field, enabling direct integration in the office.

使用Zeno Office的“ EasyIn”工作流程仅一键即可轻松导入使用Zeno 10捕获的灌溉网络的数据。最新数据直接传输到ESRI ARCMAP。此自动化过程非常易于维护和管理，ARCMAP生成了包含QC和处理数据的最终地图。

For further map updates that require new survey operations for the irrigation network, El Concorde Construction export features from ArcMap to Zeno Field using the equally simple ‘EasyOut’ wizard. Once the surveyors go out, they take the updated data set into the field.

El Concorde Construction的项目和地理工程师Mohammed Al-Eswid指出：“ Leica Zeno可以很容易地被带到调查地点。用户可以通过简单地拍摄手持式图片并输入已在现场测量并由Esri Arcgis进行更新的数据来收集信息。最好的事情是，您不需要几天回到办公室。”

有效的工作流程
A single spatial database for each project was designed and Leica Zeno Office software was used to create and manage a database containing all mandatory attribute fields requested, as well as other information, such as site photographs. It also contains drop down lists to improve data quality and speed of collection. The entire projects were surveyed by a specialist team of surveyors who collected 40,000 features.
