基于Snakes模型的移位算法是一种适合线状地图要素移位的全局最优化算法,该算法的移位效果在一定程度上依赖于Snakes模型形状参数(弹性参数α和刚性参数β)的设置,但目前仍缺少定量化的参数设置方法。为改善该算法的移位效果,该文提出了一种顾及道路要素等级属性和局部弯曲特征的Snakes模型形状参数优化设置方法。该方法分别建立了Snakes模型的形状参数与道路等级属性、道路内部各段弯曲曲率之间的定量关系,从而可在移位过程中更好地顾及道路要素的语义特征和图形特征。实验中,采用ArcGIS Engine二次开发实现了相应的道路网移位程序,并对某山区部分道路网进行移位处理,与原有算法相比,移位效果有所改善。  相似文献

地图综合是当前国际GIS和制图学领域的一个难题。化简是地图综合的一个基本操作算子,线要素是地图综合操作的主要对象,该文主要研究地图线要素的化简问题。首先,从算法的适用范围、阈值设置等方面分析了现有算法的优点,重点阐述了一种常用的弧比弦算法,并指出了其在化简过程中存在的不足。然后,基于地图曲线的空间认知特征,提出了一种改进弧比弦算法。该算法能够更好地保持曲线的特征点和曲线的几何形态,避免阈值的设置问题。在算法评价上,采用3种定量评价指标,即:偏移平均值、偏移量中值和面积变形值,对改进的弧比弦算法与现有经典算法进行了比较分析。最后,通过算例分析验证了该算法的可行性、有效性和健壮性。  相似文献

基于纹理特征与数学形态学的高分辨率影像城市道路提取   总被引:5,自引:0,他引:5  
从遥感影像上提取道路面临如下问题:根据光谱特征分类的图像存在建筑物与道路混淆,受交通工具、行道树等影响易产生道路中的孔洞与道路边缘的毛刺等。该文利用南京市IKONOS高分辨率影像丰富的空间纹理信息,将纹理信息加入原始波段参与分类,可以解决建筑物与道路的混淆问题。另外,道路具有丰富的形态特征,应用数学形态学的相关算法和形状指数,可以很好地去除道路提取过程中产生的各种噪声。  相似文献

为了促使无线通信基站定位技术进一步用于解决用户定位信息与空间地图信息匹配的问题,该文提出了一种基于话单的道路定位算法:针对移动场景,在基站定位过程中结合话单定位参数信息和空间道路信息,实现了将用户直接定位到道路上的目标;对矢量道路进行解析并采用网格索引技术建立索引,设计过滤条件对算法进行优化,提高了定位的求解速度。以实际话单进行测试,得到了合适的网格化步长参数,通过对定位精度进行分析,证明了该算法的可行性和有效性。该算法可进一步提高基站定位技术的应用范围,对5G及物联网技术也将有重要意义。  相似文献

一种基于面积平衡约束的图斑化简算法   总被引:1,自引:0,他引:1  
保持综合前后各地类土地面积平衡是土地利用数据综合的基本原则.地类图斑是面积统计的最小单元,用常规的线化简算法不但难以保证图斑的地理特性,而且会给面积统计带来不确定性.该文提出一种能够使图斑化简前后面积保持绝对平衡的化简算法,该算法给出了求取图斑群和岛图斑的地理特征点、几何特征点的相关方法,对被特征点分割的综合子弧段运用直线面积平衡和参数曲线面积平衡两种求取平衡线的方式进行化简,基本原理是综合前后弧段切割它们自身的包络矩形面积比相等,且综合后的弧段须落入综合前子弧段的误差缓冲区内.实验表明,该算法不但能保持图斑的形态特征,而且能保持图斑化简前后面积绝对相等.  相似文献

地理信息系统对矢量数据进行处理和应用的过程中,数据压缩是一个必须解决的问题,而通常采用的两种经典曲线数据压缩法:垂距限值法和道格拉斯-普克算法,都存在线段空间偏移过大以及面积偏差不可控的问题。利用曲线空间直线拟合的方法对曲线段中心轴进行空间逼近,通过增加面积偏差限值,提出了面积偏差控制下的矢量数据压缩算法,并以上海市崇明县岛屿边界轮廓矢量为例对该算法进行了验证。试验表明该方法对于解决两种经典压缩算法线段空间偏移过大以及面积偏差不可控的问题效果明显。  相似文献

基于MCR模型的卡拉麦里地区生态安全格局变化研究   总被引:1,自引:0,他引:1  
《干旱区地理》2021,44(5):1396-1406
随着生产力的发展,人类在开发活动中导致的植被破坏、水源污染、土壤污染等生态环境问题日益突出,人类活动与自然环境之间的矛盾和保障人类社会的可持续发展已经成为急需解决的问题。利用最小累积阻力模型(MCR)对1990—2019年卡拉麦里地区的生态安全格局变化规律进行分析,并结合元胞自动机-马尔可夫模型(CA-Markov)对2025年本地区的生态安全格局进行预测。结果表明:(1)将卡拉麦里地区的生态安全格局分为安全区、低安全区及不安全区,安全区的面积在2010—2015年萎缩至3237.31 km~2,主要转化为低安全区及不安全区,这一时期的人类活动严重影响到了本区的生态环境。(2)2019年,安全区面积为6265.91 km~2,低安全区及不安全区基本恢复为自然状态,生态治理工作取得良好效果。(3)预测可知,2025年卡拉麦里地区景观格局变化不大,仍以草地、未利用地为主。生态安全区面积6421.88 km~2,低安全区及不安全区面积有继续下降趋势。(4)在卡山保护区中部的交通路线附近形成了一条带状低安全区,将成为今后保护区生态监测与保护的重点区域。  相似文献

以2003年5月29日福州市LandsmETM+影像为数据源,对2种地表温度空间降尺度算法——EM算法和HUTS算法进行实验、比较与分析,EM算法是利用高空间分辨率的地表比辐射率对低空间分辨率的亮度温度影像进行调节,从而达到提高热红外影像空间分辨率的目的;HUTS算法则是引入了归一化差异植被指数NDVI和地表反照率d,通过在低空间分辨率拟合二者与地表温度LST之间的关系,然后根据其尺度不变性,将该关系应用到高空间分辨率的影像上,从而达到提高热红外影像空间分辨率的目的.研究结果表明:1)2种算法所得结果影像都能在有效提高空间分辨率的同时较好地保持了原始地表温度影像的空间分布特征,达到了较好的降尺度效果;2)以RMSE为定量评价指标,HUTS算法要略优于EM算法,其中,EM算法的RMSE为1.2494,而HUTS算法仅为0.9869.  相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world's largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.  相似文献
