StaMPS-Visualizer ：由thho开发的用于可视化由StaMPS / MTI处理的DInSAR结果。
github地址：StaMPS-Visualizer

使用StaMPS_Visualizer需要配置好StaMPS，并安装好R和Rstudio

Ubuntu中安装StaMPS
StaMPS-Visualizer 安装步骤–在linux系统中安装R和Rstudio

1 StaMPS_Visualizer 展示基线图

StaMPS_Visualizer 可以展示PS基线和SBAS基线

1.1 从SNAP中导出PS基线和SBAS基线数据

打开SNAP，导入stack数据，View –> Tool Windows –> Radar –> InSAR Stack
选择Baseline ，点击右边上面的copy，在文字编辑器中编辑，第一行cohere为1，其他的都是0
csv里面不要有空格
另存为.csv格式，放在/StaMPS_Visualizer-master/input/baseline_info文件夹下面

1.2 展示基线连接图

包括PS基线和SBAS基线
打开ui.R
点击Run App
可以选择数据源，展示PS和SBAS基线，调整时空基线长度，时间基线单位为天day，空间为米m
也可以在浏览器中打开Open in Browser

2 StaMPS_Visualizer 展示检测点形变数据

2.1 制图并导出csv

在matlab中使用ps_plot制图，具体命令如下

from https://thho.shinyapps.io/StaMPS_Visualizer/#exportbl
% the 'v-doa' parameter is an example you can change it to your needs
ps_plot('v-doa', 'ts'); % a new window will open
% in the new window select a radius and location of the radius center to select the PS to exportload parms.mat;% the 'v-doa' parameter is an example you can change it to your needs
% but be sure that you use the same paramters as above in the ps_plot()!
ps_plot('v-doa', -1);load ps_plot_v-doa.mat;
lon2_str = cellstr(num2str(lon2));
lat2_str = cellstr(num2str(lat2));
lonlat2_str = strcat(lon2_str, lat2_str);lonlat_str = strcat(cellstr(num2str(lonlat(:,1))), cellstr(num2str(lonlat(:,2))));
ind = ismember(lonlat_str, lonlat2_str);disp = ph_disp(ind);
disp_ts = ph_mm(ind,:);
export_res = [lonlat(ind,1) lonlat(ind,2) disp disp_ts];metarow = [ref_centre_lonlat NaN transpose(day)-1];
k = 0;
export_res = [export_res(1:k,:); metarow; export_res(k+1:end,:)];
export_res = table(export_res);% you can specify the location and name of the .csv export by renaming the second parameter
writetable(export_res,'stamps_tsexport.csv')
