【摘要】：獲取科研數(shù)據(jù)是科學研究中重要基礎性工作,尤其在自然科學領域,時常涉及到野外數(shù)據(jù)的獲取。當前,智能移動電子設備和移動GIS的發(fā)展,已經(jīng)逐漸滲透到了各行各業(yè)。 論文以Android平臺為基礎,結(jié)合移動GIS在LBS領域的前沿技術,開發(fā)出了普遍適用于科研工作的野外數(shù)據(jù)采集系統(tǒng)。論文的目的是將移動GIS技術與智能設備相結(jié)合并應用到野外數(shù)據(jù)采集工作中,改進傳統(tǒng)采集方法,提高野外數(shù)據(jù)采集的作業(yè)效率。 論文梳理了野外數(shù)據(jù)采集系統(tǒng)方面相關研究進展和已有的野外數(shù)據(jù)采集系統(tǒng),并評述了已有的各類型系統(tǒng)的優(yōu)缺點,介紹了當前移動GIS的發(fā)展概況,尤其是當前在移動GIS領域中的LBS服務的發(fā)展前沿。在深入調(diào)研野外數(shù)據(jù)采集的用戶需求的基礎上,基于Android平臺設計和開發(fā)了野外數(shù)據(jù)采集系統(tǒng),該系統(tǒng)能滿足普遍的野外科研數(shù)據(jù)采集需求。該系統(tǒng)包含基礎數(shù)據(jù)錄入、地圖展示采樣點、地圖定位及路徑查詢、數(shù)據(jù)智能導出等功能。經(jīng)過系統(tǒng)測試,本文設計的野外數(shù)據(jù)采集系統(tǒng)安全可靠、使用方便、適用范圍廣、定位精確,基本能夠滿足科研用戶的一般需求。 野外數(shù)據(jù)采集系統(tǒng)能夠使野外數(shù)據(jù)采集工作數(shù)字化,既提高了野外工作效率,又減少了重復勞動,為科研過程中的外業(yè)采集工作增添了便利,具有一定的實踐及應用價值。
[Abstract]:Obtaining scientific research data is an important basic work in scientific research, especially in the field of natural science, which often involves the acquisition of field data. At present, the development of intelligent mobile electronic devices and mobile GIS has gradually penetrated into various industries. On the basis of Android platform and the advanced technology of mobile GIS in the field of LBS, a field data acquisition system is developed, which is widely used in scientific research. The purpose of this paper is to combine the mobile GIS technology with the intelligent equipment and apply it to the field data collection, improve the traditional collection method and improve the working efficiency of the field data collection. In this paper, the research progress of field data acquisition system and the existing field data acquisition system are reviewed, and the advantages and disadvantages of the existing types of data acquisition system are reviewed, and the development of current mobile GIS is introduced. Especially, the development of LBS services in the field of mobile GIS. The field data acquisition system is designed and developed based on Android platform on the basis of deep investigation of the users' requirements of field data acquisition. The system can meet the general demand of field scientific research data collection. The system includes basic data input, map display sampling points, map location and path query, data intelligent export and other functions. After system test, the field data acquisition system designed in this paper is safe and reliable, convenient to use, applicable to a wide range of applications, accurate positioning, can basically meet the general needs of scientific research users. The field data acquisition system can make the field data acquisition work digitalized, not only improves the field work efficiency, but also reduces the repeated work, which adds convenience to the field collection work in the process of scientific research, and has certain practice and application value.
