## Is it possible host a custom google map on a website using an iframe or similar?

Im trying to embed an google map onto a company website using the method.

This works fine, but the resulting maps show a competitor who is geographically close to the company whos website i am working on.

We dont want someone to visit the website i am working on and see a competitors name.

Eg. please see attached screenshot. (FYI this is a random screenshot i have taken from google maps, i am not related with any of these companies) If i was working on “Company A”‘s i wouldn’t want to host a google map showing “Company B”.

Accordingly is it possible to make a custom google map removing select certain pins that i dont want ?

## Why if T is normal linear map, then image of T if the same as image of T*?

If $$T$$ is a normal linear map from vector space $$V$$ to itself, then image of $$T$$ is the same as image of $$T*$$.

Can anyone help me to prove this?

## java – Cannot set latitude and longitude to a Google Map android studio

Im implementing a google map with showing the current location of the user. But whenever i run the program it show me `java.lang.NullPointerException: Attempt to invoke virtual method 'double java.lang.Double.doubleValue()' on a null object reference`. Im trying to set the value for longitude and latitude with my other class’s `get` method, `sosrecord.getLatitude` and `sosrecord.getLongitude`.

My get see class

``````package com.example.sossystem;

public class SosRecords {

String RecordID;
String FullName;
String PhoneNumber;
Double Latitude;
Double Longitude;
String CallFor;

public SosRecords(){

}

public SosRecords(String fullName, String phoneNumber, String userEmail, Double latitude, Double longitude, String callFor) {

FullName = fullName;
PhoneNumber = phoneNumber;
Latitude = latitude;
Longitude = longitude;
CallFor = callFor;
}

public String getRecordID() {
return RecordID;
}

public void setRecordID(String recordID) {
RecordID = recordID;
}

public String getFullName() {
return FullName;
}

public void setFullName(String fullName) {
FullName = fullName;
}

public String getPhoneNumber() {

}

public void setPhoneNumber(String phoneNumber) {

My Main function

## popup – How to handle map section navigation in mobile

Given a section which takes full height of the device’s viewport and have the following controls at disposal of the user:

• Can pan through the map within a certain boundary (a country);
• Can select an state to view it’s information;
• Can input or select a city’s name to view it’s information;
• Can see only one of the informations simultaneously (accordion).

How does one accommodate these functionalities in a handheld device (i.e. mobile phones)? Without annoying the user with:

• Mistakenly get his touch input while scrolling down the page to pan the map (“scroll hijack”?);
• Visual pollution with too much screen elements (e.g.: Map + Information panel);
• Very small font size.

Here’s what the designer came up with:

Disclaimer: he/she doesn’t have much experience with UX/UI nor have I.

I came up with this prototype*:

Initial state State selection state City selection state

But I don’t think it is the “best” solution, for the following reasons:

• The user don’t see the selection on the map, it would just popup above it, giving the animation of the selection in a window of 200 milliseconds (maybe delay it to ~750 milliseconds);
• The user’s pan interaction is removed, because the panel is now above it.

But it have its pros:

• The user is given space top and bottom to scroll the rest of the page, the section itself is about 75% of the device’s total viewport height;
• No extra information noise/pollution on the initial state (inert, i.e.: no first interaction);
• The user is given an option to exit the information panel (top right corner).

My initial question remains, as I’m not too confident with this “solution” that I’ve provided. I hope it isn’t too subjective and there are better solution for this.

Here is a preview on desktop:

Initial state State selection state City selection state

The most important elements of the map section are:

• The map itself;
• The information panel.

English is not my first language so any edit/suggestion is appreciated.

## ag.algebraic geometry – Cycle class map for singular varieties

I am reading the cycle class map for singular projective varieties as mentioned by Laterveer in this article (see Definition $$1$$). The article does not define the map but refers to an article of Totaro, which also does not define the map but refers to the article “Non-archimedean Arakelov theory” by Bloch, Gillet and Soule, which is published in JAG in 1995 and is not available online. Can someone give a bit more details on this map (or an alternate reference)? For example, the authors say that this map is functorial. I do not quite understand what this means, as the cohomology group is functorial under pull-back and the Chow-group is functorial under proper pushforward and flat pull-back? Moreover, does the image of the composition
$$mathrm{A}^p(X) xrightarrow{cl} mathrm{Gr}^{W}_{2p}H^{2p}(X,mathbb{Q}) xrightarrow{rest.} mathrm{Gr}^{W}_{2p}H^{2p}(X_{mathrm{smooth}},mathbb{Q})$$
is the same the usual cycle class map
$$A^p(X_{mathrm{smooth}}) xrightarrow{cl} H_{2n-2p}^{mathrm{BM}}(X_{mathrm{smooth}}) xrightarrow{P.D.} H^{2p}(X_{mathrm{smooth}})?$$
What is the pull-back of the image of the singular cycle class map to the cohomology on
the resolution of singularities?

## Why does the function \$f(x) = x^2\$ map out all positive values for the codomain?

If we take

$$x^2=y$$

then solving x in terms of y is

$$x=pm sqrt{y}$$

so that all negative values of y would be mapped to a complex plane rather than the real cartesian plane.

However, the function doesn’t specify order of operations for x. So for example, if $$f(x)=(x^2)$$, then the codomain is mapped out to all positive real numbers due to order of operations with parenthesis. With $$f(x)=x^2$$, for example if we take -1 as an input, $$-1^2=pmsqrt{-1}$$ due to the absence of parenthesis. However, this would mean there could be no negative domain for $$f(x)=x^2$$, because all negative values would map out to complex numbers.

This where I get more confused. If we take the domain to be 1 for instance, then

$$1^2=1$$

therefore,

$$1=pmsqrt{1}$$

$$1=pm1$$

which means that the domain of 1 maps out to a codomain of 1 or -1, which is not true for $$f(x)=x^2$$ since it maps out all positive numbers.

I am wondering if I could get some guidance on this, I feel like I really overthinking this.

Se que se puede añadir en editar extent en el atlas una expresión tal que xmin (geometría (getFeature (‘marco’, ‘gid’, 1))) ymin (geometría (getFeature (‘marco’, ‘gid’, 1))) xmax (geometría (getFeature (‘marco’, ‘gid’, 1))) ymax (geometría (getFeature (‘frame’, ‘gid’, 1))), pero no se como implementarlo en mi caso.

Cualquier ayuda es bien recibida.
Gracias.
