Issues related to the add_raster function

zwy1502 commented 3 months ago

Description

I want to visualize my scene image

What I Did

import geemap
import ee
geemap.set_proxy(port='17890')
Map = geemap.Map()
Map.add_tile_layer(
    url="https://mt1.google.com/vt/lyrs=y&x={x}&y={y}&z={z}&scale=2",
    name="HD Google Basemap",
)
Map

# 指定本地栅格影像的路径
filename = r"D:\research\fenlei\尼罗河\NLH\水体分类median.tif"

# 定义可视化参数
vis_params = {'min': 0, 'max': 1, 'palette': ['green', 'blue']}

# 添加本地栅格影像到地图上
Map.add_raster(filename, vis_params=vis_params, layer_name='Local Image')

# 添加颜色条到地图
Map.add_colorbar(vis_params, label='Value')

# 显示地图
Map

Code error

This is your localtileserver installtion issue. Try import localtileserver. If it does not work, create a new fresh conda env and use the following command to install packages.

https://localtileserver.banesullivan.com/installation/index.html#installing-with-conda

conda install -c conda-forge localtileserver geemap

Teacher, I installed Geemap according to the code in your book and ran these codes separately: conda create -n gee python conda activate gee conda install -c conda-forge mamba mamba install -c conda-forge geemap pygis

In the following answer, I refer to the environment in which the four lines of code run as Gee

After running these codes, I did not take any other actions. Currently, I have provided you with feedback that the issue is based on reinstalling a Gee environment from my four lines of code and running it again: Map. add_raster (file name,...), vis_params=vis_params, layer_name='Local Image')。 The program will report an error about the localileserver library.

I listened to what you said, teacher. First, I tried importing localileserver, but the program still reported an error:

Currently, I have two questions: How should this problem be solved? The teacher's solution is to run the following four lines of code to generate a new conda environment and try again, right? conda create -n gee2 python conda activate gee2 conda install -c conda-forge mamba mamba install -c conda-forge localtileserver geemap

I have heard a lesson from the teacher at East China Normal University, who said that installing all the Geemap libraries and dependencies only requires installing Geemap and pygis, so that all the Geemap functions can be used. I did this, but the fact that addraster is not allowed does not mean that a new command generation environment is needed now? For example, the current command code is no longer: mamba install -c conda-forge geemap pygis But: mamba install - c conda forge localtileserver geemap， Am I right?

I hope the teacher can answer my question the most: Teacher, I have read and purchased the books you published on CSDN, and heard about the courses you taught at East China Normal University in Shanghai. You all said that running these four lines of code can use all the functions of Geemap: conda create -n gee python conda activate gee conda install -c conda-forge mamba mamba install -c conda-forge geemap pygis

But now is it necessary to change the last line to mamba install - c conda forge localtileserver geemap

zwy1502 commented 3 months ago

What should I do if I want to use this addraster function in the Gee environment generated by the following four lines of code? Or is it necessary to reinstall a new environment? conda create -n gee python conda activate gee conda install -c conda-forge mamba mamba install -c conda-forge geemap pygis
